Jon Mason 47f01db44b vxge: enable rxhash 
Enable RSS hashing and add ability to pass up the adapter calculated rx
hash up the network stack (if feature is available).  Add the ability to
enable/disable feature via ethtool, which requires that the adapter is
not running at the time.  Other miscellaneous cleanups and fixes
required to get RSS working.

* @tx_ttl_frms: Count of successfully transmitted MAC frames
* @tx_ttl_octets: Count of total octets of transmitted frames, not including

* total octets of transmitted frames, including framing characters,
* multiply PORTn_TX_TTL_FRMS by 8 and add it to this stat (unless
* otherwise configured, this stat only counts frames that have
* 8 bytes of preamble for each frame). This stat can be configured
* (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count everything
* including the preamble octets.
* @tx_data_octets: Count of data and padding octets of successfully transmitted
* frames.
* @tx_mcast_frms: Count of successfully transmitted frames to a group address
* other than the broadcast address.
* @tx_bcast_frms: Count of successfully transmitted frames to the broadcast
* group address.
* @tx_ucast_frms: Count of transmitted frames containing a unicast address.
* Includes discarded frames that are not sent to the network.
* @tx_tagged_frms: Count of transmitted frames containing a VLAN tag.
* @tx_vld_ip: Count of transmitted IP datagrams that are passed to the network.
* @tx_vld_ip_octets: Count of total octets of transmitted IP datagrams that
* are passed to the network.
* @tx_icmp: Count of transmitted ICMP messages. Includes messages not sent
* due to problems within ICMP.
* @tx_tcp: Count of transmitted TCP segments. Does not include segments
* containing retransmitted octets.
* @tx_rst_tcp: Count of transmitted TCP segments containing the RST flag.
* @tx_udp: Count of transmitted UDP datagrams.
* @tx_parse_error: Increments when the TPA is unable to parse a packet. This
* generally occurs when a packet is corrupt somehow, including
* packets that have IP version mismatches, invalid Layer 2 control
* fields, etc. L3/L4 checksums are not offloaded, but the packet
* is still be transmitted.
* @tx_unknown_protocol: Increments when the TPA encounters an unknown
* protocol, such as a new IPv6 extension header, or an unsupported
* Routing Type. The packet still has a checksum calculated but it
* may be incorrect.
* @tx_pause_ctrl_frms: Count of MAC PAUSE control frames that are transmitted.
* Since, the only control frames supported by this device are
* PAUSE frames, this register is a count of all transmitted MAC
* control frames.
* @tx_marker_pdu_frms: Count of Marker PDUs transmitted
* on this Aggregation port.
* @tx_lacpdu_frms: Count of LACPDUs transmitted on this Aggregation port.
* @tx_drop_ip: Count of transmitted IP datagrams that could not be passed to
* the network. Increments because of:
* 1) An internal processing error
* (such as an uncorrectable ECC error). 2) A frame parsing error
* during IP checksum calculation.
* @tx_marker_resp_pdu_frms: Count of Marker Response PDUs transmitted on this
* Aggregation port.
* @tx_xgmii_char2_match: Maintains a count of the number of transmitted XGMII
* characters that match a pattern that is programmable through
* register XMAC_STATS_TX_XGMII_CHAR_PORTn. By default, the pattern
* is set to /T/ (i.e. the terminate character), thus the statistic
* tracks the number of transmitted Terminate characters.
* @tx_xgmii_char1_match: Maintains a count of the number of transmitted XGMII
* characters that match a pattern that is programmable through
* register XMAC_STATS_TX_XGMII_CHAR_PORTn. By default, the pattern
* is set to /S/ (i.e. the start character),
* thus the statistic tracks
* the number of transmitted Start characters.
* @tx_xgmii_column2_match: Maintains a count of the number of transmitted XGMII
* columns that match a pattern that is programmable through register
* XMAC_STATS_TX_XGMII_COLUMN2_PORTn. By default, the pattern is set
* to 4 x /E/ (i.e. a column containing all error characters), thus
* the statistic tracks the number of Error columns transmitted at
* any time. If XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is
* set to 1, then this stat increments when COLUMN2 is found within
* 'n' clocks after COLUMN1. Here, 'n' is defined by
* XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set
* to 0, then it means to search anywhere for COLUMN2).
* @tx_xgmii_column1_match: Maintains a count of the number of transmitted XGMII
* columns that match a pattern that is programmable through register
* XMAC_STATS_TX_XGMII_COLUMN1_PORTn. By default, the pattern is set
* to 4 x /I/ (i.e. a column containing all idle characters),
* thus the statistic tracks the number of transmitted Idle columns.
* @tx_any_err_frms: Count of transmitted frames containing any error that
* prevents them from being passed to the network. Increments if
* there is an ECC while reading the frame out of the transmit
* buffer. Also increments if the transmit protocol assist (TPA)
* block determines that the frame should not be sent.
* @tx_drop_frms: Count of frames that could not be sent for no other reason
* than internal MAC processing. Increments once whenever the
* transmit buffer is flushed (due to an ECC error on a memory
* descriptor).
* @rx_ttl_frms: Count of total received MAC frames, including frames received
* with frame-too-long, FCS, or length errors. This stat can be
* configured (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count
* everything, even "frames" as small one byte of preamble.
* @rx_vld_frms: Count of successfully received MAC frames. Does not include
* frames received with frame-too-long, FCS, or length errors.
* @rx_offload_frms: Count of offloaded received frames that are passed to
* the host.
* @rx_ttl_octets: Count of total octets of received frames, not including
* framing characters (i.e. less framing bits). To determine the
* total octets of received frames, including framing characters,
* multiply PORTn_RX_TTL_FRMS by 8 and add it to this stat (unless
* otherwise configured, this stat only counts frames that have 8
* bytes of preamble for each frame). This stat can be configured
* (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count everything,

* @rx_offload_octets: Count of total octets, not including framing
* characters, of offloaded received frames that are passed
* to the host.
* @rx_vld_mcast_frms: Count of successfully received MAC frames containing a
* nonbroadcast group address. Does not include frames received
* with frame-too-long, FCS, or length errors.
* @rx_vld_bcast_frms: Count of successfully received MAC frames containing
* the broadcast group address. Does not include frames received
* with frame-too-long, FCS, or length errors.
* @rx_accepted_ucast_frms: Count of successfully received frames containing
* a unicast address. Only includes frames that are passed to
* the system.
* @rx_accepted_nucast_frms: Count of successfully received frames containing
* a non-unicast (broadcast or multicast) address. Only includes
* frames that are passed to the system. Could include, for instance,
* non-unicast frames that contain FCS errors if the MAC_ERROR_CFG
* register is set to pass FCS-errored frames to the host.
* @rx_tagged_frms: Count of received frames containing a VLAN tag.
* @rx_long_frms: Count of received frames that are longer than RX_MAX_PYLD_LEN
* + 18 bytes (+ 22 bytes if VLAN-tagged).
* @rx_usized_frms: Count of received frames of length (including FCS, but not
* framing bits) less than 64 octets, that are otherwise well-formed.
* In other words, counts runts.
* @rx_osized_frms: Count of received frames of length (including FCS, but not

* is full and the receive path is backing up.
* @rx_red_discard: Count of received frames that are discarded because of RED
* (Random Early Discard).
* @rx_xgmii_ctrl_err_cnt: Maintains a count of unexpected or misplaced control

* Only increments the count by one for each XGMII column.
* @rx_xgmii_data_err_cnt: Maintains a count of unexpected control characters
* during normal data transmission. If the Reconciliation Sublayer
* (RS) receives a control character, other than a terminate control

* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
* to /E/ (i.e. the error character), thus the statistic tracks the
* number of Error characters received at any time.
* @rx_xgmii_err_sym: Count of the number of symbol errors in the received
* XGMII data (i.e. PHY indicates "Receive Error" on the XGMII).
* Only includes symbol errors that are observed between the XGMII
* Start Frame Delimiter and End Frame Delimiter, inclusive. And
* only increments the count by one for each frame.
* @rx_xgmii_column1_match: Maintains a count of the number of XGMII columns
* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_COLUMN1_PORTn. By default, the pattern is set
* to 4 x /E/ (i.e. a column containing all error characters), thus
* the statistic tracks the number of Error columns received at any
* time.
* @rx_xgmii_char2_match: Maintains a count of the number of XGMII characters
* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
* to /E/ (i.e. the error character), thus the statistic tracks the
* number of Error characters received at any time.
* @rx_local_fault: Maintains a count of the number of times that link
* transitioned from "up" to "down" due to a local fault.
* @rx_xgmii_column2_match: Maintains a count of the number of XGMII columns
* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_COLUMN2_PORTn. By default, the pattern is set
* to 4 x /E/ (i.e. a column containing all error characters), thus
* the statistic tracks the number of Error columns received at any
* time. If XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is set
* to 1, then this stat increments when COLUMN2 is found within 'n'
* clocks after COLUMN1. Here, 'n' is defined by
* XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set to
* 0, then it means to search anywhere for COLUMN2).
* @rx_jettison: Count of received frames that are jettisoned because internal
* buffers are full.
* @rx_remote_fault: Maintains a count of the number of times that link
* transitioned from "up" to "down" due to a remote fault.
