virtio_net XDP support expects receive buffers to be contiguous.
If this is not the case we enable a slowpath to allow connectivity
to continue but at a significan performance overhead associated with
linearizing data. To make it painfully aware to users that XDP is
running in a degraded mode we throw an xdp buffer error.
To linearize packets we allocate a page and copy the segments of
the data, including the header, into it. After this the page can be
handled by XDP code flow as normal.
Then depending on the return code the page is either freed or sent
to the XDP xmit path. There is no attempt to optimize this path.
This case is being handled simple as a precaution in case some
unknown backend were to generate packets in this form. To test this
I had to hack qemu and force it to generate these packets. I do not
expect this case to be generated by "real" backends.

This adds support for the XDP_TX action to virtio_net. When an XDP
program is run and returns the XDP_TX action the virtio_net XDP
implementation will transmit the packet on a TX queue that aligns
with the current CPU that the XDP packet was processed on.
Before sending the packet the header is zeroed. Also XDP is expected
to handle checksum correctly so no checksum offload support is
provided.

XDP requires using isolated transmit queues to avoid interference
with normal networking stack (BQL, NETDEV_TX_BUSY, etc). This patch
adds a XDP queue per cpu when a XDP program is loaded and does not
expose the queues to the OS via the normal API call to
netif_set_real_num_tx_queues(). This way the stack will never push
an skb to these queues.
However virtio/vhost/qemu implementation only allows for creating
TX/RX queue pairs at this time so creating only TX queues was not
possible. And because the associated RX queues are being created I
went ahead and exposed these to the stack and let the backend use
them. This creates more RX queues visible to the network stack than
TX queues which is worth mentioning but does not cause any issues as
far as I can tell.

This adds XDP support to virtio_net. Some requirements must be
met for XDP to be enabled depending on the mode. First it will
only be supported with LRO disabled so that data is not pushed
across multiple buffers. Second the MTU must be less than a page
size to avoid having to handle XDP across multiple pages.
If mergeable receive is enabled this patch only supports the case
where header and data are in the same buf which we can check when
a packet is received by looking at num_buf. If the num_buf is
greater than 1 and a XDP program is loaded the packet is dropped
and a warning is thrown. When any_header_sg is set this does not
happen and both header and data is put in a single buffer as expected
so we check this when XDP programs are loaded. Subsequent patches
will process the packet in a degraded mode to ensure connectivity
and correctness is not lost even if backend pushes packets into
multiple buffers.
If big packets mode is enabled and MTU/LRO conditions above are
met then XDP is allowed.
This patch was tested with qemu with vhost=on and vhost=off where
mergeable and big_packet modes were forced via hard coding feature
negotiation. Multiple buffers per packet was forced via a small
test patch to vhost.c in the vhost=on qemu mode.

Before, encx24j600_rx_packets did not update encx24j600_priv's next_packet
member when an error occurred during packet handling (either because the
packet's RSV header indicates an error or because the encx24j600_receive_packet
method can't allocate an sk_buff).
If the next_packet member is not updated, the ERXTAIL register will be set to
the same value it had before, which means the bad packet remains in the
component's memory and its RSV header will be read again when a new packet
arrives. If the RSV header indicates a bad packet or if sk_buff allocation
continues to fail, new packets will be stored in the component's memory until
that memory is full, after which packets will be dropped.
The SETPKTDEC command is always executed though, so the encx24j600 hardware has
an incorrect count of the packets in its memory.
To prevent this, the next_packet member should always be updated, allowing the
packet to be skipped (either because it's bad, as indicated in its RSV header,
or because allocating an sk_buff failed). In the allocation failure case, this
does mean dropping a valid packet, but dropping the oldest packet to keep as
much memory as possible available for new packets seems preferable to keeping
old (but valid) packets around while dropping new ones.

The timer handling in this driver is broken in several ways:
- corkscrew_open() initializes and arms a timer before requesting the
device interrupt. If the request fails the timer stays armed.
A second call to corkscrew_open will unconditionally reinitialize the
quued timer and arm it again. Also a immediate device removal will leave
the timer queued because close() is not called (open() failed) and
therefore nothing issues del_timer().
The reinitialization corrupts the link chain in the timer wheel hash
bucket and causes a NULL pointer dereference when the timer wheel tries
to operate on that hash bucket. Immediate device removal lets the link
chain poke into freed and possibly reused memory.
Solution: Arm the timer after the successful irq request.
- corkscrew_close() uses del_timer()
On close the timer is disarmed with del_timer() which lets the following
code race against a concurrent timer expiry function.
Solution: Use del_timer_sync() instead
- corkscrew_close() calls del_timer() unconditionally
del_timer() is invoked even if the timer was never initialized. This
works by chance because the struct containing the timer is zeroed at
allocation time.
Solution: Move the setup of the timer into corkscrew_setup().

Instead of having individual PHY drivers set the SUPPORTED_Pause and
SUPPORTED_Asym_Pause flags, phylib itself should set those flags,
unless there is a hardware erratum or other special case. During
autonegotiation, the PHYs will determine whether to enable pause
frame support.
Pause frames are a feature that is supported by the MAC. It is the MAC
that generates the frames and that processes them. The PHY can only be
configured to allow them to pass through.
This commit also effectively reverts the recently applied c7a61319
("net: phy: dp83848: Support ethernet pause frames").
So the new process is:
1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause
and SUPPORTED_AsymPause bits in phydev->supported. This indicates that
the PHY supports pause frames.
2) The MAC driver checks phydev->supported before it calls phy_start().
If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver
sets those bits in phydev->advertising, if it wants to enable pause
frame support.
3) When the link state changes, the MAC driver checks phydev->pause and
phydev->asym_pause, If the bits are set, then it enables the corresponding
features in the MAC. The algorithm is:
if (phydev->pause)
The MAC should be programmed to receive and honor
pause frames it receives, i.e. enable receive flow control.
if (phydev->pause != phydev->asym_pause)
The MAC should be programmed to transmit pause
frames when needed, i.e. enable transmit flow control.

This patch is based on an earlier one submitted
by Jon Maxwell with the following commit message:
"We recently encountered a bug where a few customers using ibmveth on the
same LPAR hit an issue where a TCP session hung when large receive was
enabled. Closer analysis revealed that the session was stuck because the
one side was advertising a zero window repeatedly.
We narrowed this down to the fact the ibmveth driver did not set gso_size
which is translated by TCP into the MSS later up the stack. The MSS is
used to calculate the TCP window size and as that was abnormally large,
it was calculating a zero window, even although the sockets receive buffer
was completely empty."
We rely on the Virtual I/O Server partition in a pseries
environment to provide the MSS through the TCP header checksum
field. The stipulation is that users should not disable checksum
offloading if rx packet aggregation is enabled through VIOS.
Some firmware offerings provide the MSS in the RX buffer.
This is signalled by a bit in the RX queue descriptor.
