i40evf: Fix VLAN features · c4445aed

由 Mitch Williams 提交于 3月 18, 2016

Users of ethtool were being given the mistaken impression that this
driver was able to change its VLAN tagging features, and were
disappointed that this was not actually the case. Implement
ndo_fix_features method so that we can adjust these flags as needed to
avoid false impressions.

i40e: remove redundant check on vsi->active_vlans · afb8ece4

net/core/dev: Warn on a too-short GRO frame · 4da46ceb

由 Aaron Conole 提交于 4月 02, 2016

When signaling that a GRO frame is ready to be processed, the network stack
correctly checks length and aborts processing when a frame is less than 14
bytes. However, such a condition is really indicative of a broken driver,
and should be loudly signaled, rather than silently dropped as the case is
today.

Convert the condition to use net_warn_ratelimited() to ensure the stack
loudly complains about such broken drivers.

ibmvnic: map L2/L3/L4 header descriptors to firmware · ad7775dc

由 Thomas Falcon 提交于 4月 01, 2016

Allow the VNIC driver to provide descriptors containing
L2/L3/L4 headers to firmware.  This feature is needed
for greater hardware compatibility and enablement of checksum
and TCP offloading features.

A new function is included for the hypervisor call,
H_SEND_SUBCRQ_INDIRECT, allowing a DMA-mapped array of SCRQ
descriptor elements to be sent to the VNIC server.

These additions will help fully enable checksum offloading as
well as other features as they are included later.

net: bcmgenet: cleanup for dmadesc_set() · 7ee40625

由 Petri Gynther 提交于 4月 05, 2016

dmadesc_set() is used for setting the Tx buffer DMA address, length,
and status bits on a Tx ring descriptor when a frame is being Tx'ed.

Always set the Tx buffer DMA address first, before updating the length
and status bits, i.e. giving the Tx descriptor to the hardware.

The reason this is a cleanup rather than a fix is that the hardware
won't transmit anything from a Tx ring until the TDMA producer index
has been incremented. As long as the dmadesc_set() writes complete
before the TDMA producer index write, life is good.

udp: enable MSG_PEEK at non-zero offset · 627d2d6b

由 samanthakumar 提交于 4月 05, 2016

Enable peeking at UDP datagrams at the offset specified with socket
option SOL_SOCKET/SO_PEEK_OFF. Peek at any datagram in the queue, up
to the end of the given datagram.

Implement the SO_PEEK_OFF semantics introduced in commit ef64a54f
("sock: Introduce the SO_PEEK_OFF sock option"). Increase the offset
on peek, decrease it on regular reads.

When peeking, always checksum the packet immediately, to avoid
recomputation on subsequent peeks and final read.

The socket lock is not held for the duration of udp_recvmsg, so
peek and read operations can run concurrently. Only the last store
to sk_peek_off is preserved.

====================
40GbE Intel Wired LAN Driver Updates 2016-04-05

This series contains updates to i40e and i40evf only.

Stefan converts dev_close() to ndo_stop() for ethtool offline self test,
since dev_close() causes IFF_UP to be cleared which will remove the
interface routes and addresses.

Alex bumps up the size of the transmit data buffer to 12K rather than 8K,
which provides a gain in throughput and a reduction in overhead for
putting together the frame.  Fixed an issue in the polling routines where
we were using bitwise operators to avoid the side effects of the
logical operators.  Then added support for bulk transmit clean for skbs.

Jesse fixed a sparse issue in the type casting in the transmit code and
fixed i40e_aq_set_phy_debug() to use i40e_status as a return code.

Catherine cleans up duplicated code.

Shannon fixed the cleaning up of the interrupt handling to clean up the
IRQs only if we actually got them set up.  Also fixed up the error
scenarios where we were trying to remove a non-existent timer or
worktask, which causes the kernel heartburn.

Mitch changes the notification of resets to the reset interrupt handler,
instead of the actual reset initiation code.  This allows the VFs to get
properly notified for all resets, including resets initiated by different
PFs on the same physical device.  Also moved the clearing of VFLR bit
after reset processing, instead of before which could lead to double
resets on VF init.  Fixed code comment to match the actual function name.
