2013-08-30net: fec: fix time stamping logic after napi conversionRichard Cochran
Commit dc975382 "net: fec: add napi support to improve proformance" converted the fec driver to the napi model. However, that commit forgot to remove the call to skb_defer_rx_timestamp which is only needed in non-napi drivers. (The function napi_gro_receive eventually calls netif_receive_skb, which in turn calls skb_defer_rx_timestamp.) This patch should also be applied to the 3.9 and 3.10 kernels.

This patch adds another entry (HP hs2434 Mobile Broadband) to the list of exceptional devices that require a zero length packet in order to function properly. This list was added in commit 844e88f0. The hs2434 is manufactured by Sierra Wireless, who also produces the MC7710, which the ZLP exception list was created for in the first place.

2013-08-28bnx2x: Fix move FP memory deallocationsYuval Mintz
If driver will fail to allocate all queues, it will shrink the number of queues and move the storage queue to its correct place (i.e., the last queue among the newly supported number). When changing the pointers of the new location of the FCoE queue, we need to pay special attention to the aggregations pointer - that memory is allocated during probe and released upon driver removal. Current implementation has 2 pointers pointing to the same chunk of allocated memory, meaning upon removal there will be two kfree() of the same chunk while the other won't be released.

2013-08-22ath9k_htc: Restore skb headroom when returning skb to mac80211Helmut Schaa
ath9k_htc adds padding between the 802.11 header and the payload during TX by moving the header. When handing the frame back to mac80211 for TX status handling the header is not moved back into its original position. This can result in a too small skb headroom when entering ath9k_htc again (due to a soft retransmission for example) causing an skb_under_panic oops. Fix this by moving the 802.11 header back into its original position before returning the frame to mac80211 as other drivers like rt2x00 or ath5k do.

2013-08-20bnx2x: set VF DMAE when first function has 0 supported VFsAriel Elior
There are possible HW configurations in which PFs will have SR-IOV capability but will have Max VFs set to 0 - this happens when there are Multi-Function devices where the VFs are allocated to only some of the PFs. DMAE is configured to support VFs only if the configuring PF has supported VFs. In case the first PF to be loaded will be one without supported VFs, it will not configure DMAE to the VF-supporting mode. When VFs of other PFs will be loaded later on, they will not be able to communicate with their PF. This changes the requirement for configuring DMAE for VF-supporting mode; If the device has SR-IOV capabilities there must be some PF that has max supported VFs > 0, thus it will configure the DMAE for supporting VFs.

2013-08-20bnx2x: Consider DCBX remote errorDmitry Kravkov
When publishing information via getfeatcfg(), bnx2x driver didn't consider remote errors (e.g., switch that doesn't support DCBX) when setting the error flags.

2013-08-20bnx2x: Change DCB context handlingDmitry Kravkov
After notification that DCBX configuration has ended arrived to the driver, the driver configured the FW/HW in sleepless context. As a result, it was possible to reach a race (mostly with CNIC registration) in which the configuration will return a timeout, failing to set the DCBX results correctly. This patch moves the configuration following the DCBX end into the slowpath RTNL task (i.e., sleepless context protected by the RTNL lock), allowing the configuration to cope with such races.

2013-08-20bnx2x: dropless flow control not always functionalDmitry Kravkov
Since commit 3deb816 "bnx2x: Add a periodic task for link PHY events" link state changes can be detected not only via the attention flow but also from the periodic task. If the link state will change in such a manner (i.e., via the periodic task), dropless flow-control will not be configured. This patch remedies the issue, adding the missing configuration to all required flows.

2013-08-15net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer
In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

The recent fix d9bf5f1309 "tun: compare with 0 instead of total_len" is not totally correct. Because "len" and "sizeof()" are size_t type, that means they are never less than zero.
