80605c6513 ixgbe: consolidate packet buffer allocation
Consolidate packet buffer allocation currently being
done in the DCB path and main path. This allows the
feature set and packet buffer requirements to be done
once.

This is prep work to allow DCB to coexist with other
features namely, flow director.

68c7005d66 ixgbe: improve EEPROM read/write operations
Introduce buffered read/writes which greatly improves performance on
parts with large EEPROMs.

Previously reading/writing a word requires taking/releasing of synchronization
semaphores which adds 10ms to each operation. The optimization is to
read/write in buffers, but make sure the semaphore is not held for >500ms
according to the datasheet.

Since we can't read the EEPROM page size ixgbe_detect_eeprom_page_size() is
used to discover the EEPROM size when needed and keeps the result in
word_page_size for the rest of the run time.

Use buffered reads for ethtool -e.

e09ad236fc ixgbe: DCB, misallocated packet buffer size with X540 device
The X540 device has a smaller packet buffer but the DCB configuration
never took this into account. Under stress this can result in the DMA
engine hanging and TX Unit hang occurring to reset the device. This
patch reworks the packet buffer allocation routine used for DCB on
82599 and X540 devices to account for RX packet buffer sizes.

This fixes the immediate hang. We should consolidate the various
hardware specific routines for configuring features into a single
routine. This will make it much harder to miss feature cases like
this.

45b9f509b7 ixgbe: update ntuple filter configuration
This change fixes several issues found in ntuple filtering while I was

Specifically I updated the masks to work correctly with the latest version
of ethtool, I cleaned up the exception handling and added detailed error
output when a filter is rejected, and corrected several bits that were set
incorrectly in ixgbe_type.h.

The previous version of this patch included a printk that was left over from
me fixing the filter setup.  This patch does not include that printk.

69830529b2 ixgbe: further flow director performance optimizations
This change adds a compressed input type for atr signature hash
computation.  It also drops the use of the set functions when setting up
the ATR input since we can then directly setup the hash input as two dwords
that can be stored and passed as registers.

With these changes the cost of computing the has is low enough that we can
perform a hash computation on each TCP SYN flagged packet allowing us to
drop the number of flow director misses considerably in tests such as
netperf TCP_CRR.

that only 1 packet in 20 are actually hashed upon.

Redefined pr_fmt for driver messages.
Use %pM to display MAC address.
Aligned text to better match the new format.

119fc60a2d ixgbe:add support for a new 82599 10G Base-T device
This adds support for a new copper device for 82599, device id 0x151c.
This 82599 10GBase-T device uses the PHY's internal temperature sensor
to guard against over-temp conditions. In this scenario the PHY will be
put in a low power mode and link will no longer be able to transmit or
receive any data. When this occurs, the over-temp interrupt is latched
and driver logs this error message. A HW reset or power cycle is
required to clear this status.

21ce849ba5 ixgbe: Refactor common code between 82598 & 82599 to accommodate new hardware
Some of the following MAC functions are moved from 82598 & 82599 specific
hardware files to common.[ch] to accommodate new silicon changes. Also
fixed some white space issues
 * get_san_mac_addr, check_link, set_vmdq, clear_vmdq, clear_vfta,
 * set_vfta, fc_enable, init_uta_tables

61fac744dd ixgbe: Power down PHY during driver resets
The PHY laser is still on during driver init.  It's allowing
garbage to hit our FIFO, which eventually can cause the entire
device to die.  Power down the laser while setting up the device,
and re-enable the laser before getting link.

1097cd1770 ixgbe: Fix 82599 multispeed fiber link issues due to Tx laser flapping
Fix 82599 link issues during driver load and unload test using multi-speed
10G & 1G fiber modules. When connected back to back sometime 82599 multispeed
fiber modules would link at 1G speed instead of 10G highest speed, due to a
race condition in autotry process involving Tx laser flapping. Move autotry
autoneg-37 tx laser flapping process from multispeed module init setup
to driver unload. This will alert the link partner to restart its
autotry process when it tries to establish the link with the link partner
