* be2net: bug fix on returning an invalid nic descriptorWei Yang2013-05-241-9/+4
| | | | | | | | | | | | | | | | | | | | | In function be_get_nic_desc(), it will go through the descriptor array returned from f/w. By comparing the desc_type field, it determines whether there is a nic descriptor in the array or not. In the case of no nic descriptor, this function should return NULL. The code may return an invalide descriptor, when there is no nic descriptor in the array and the desc_count is less than MAX_RESOURCE_DESC. In this case, even there is no nic descriptor, it will still return the lase descriptor since the i doesn't equal to MAX_RESOURCE_DESC. This patch fix this issue by returning the descriptor when find it and return NULL for other cases.

* tcp: xps: fix reordering issuesEric Dumazet2013-05-241-4/+6
| | | | | | | | | | | | | | | | commit 3853b5841c01a ("xps: Improvements in TX queue selection") introduced ooo_okay flag, but the condition to set it is slightly wrong. In our traces, we have seen ACK packets being received out of order, and RST packets sent in response. We should test if we have any packets still in host queue.

* virtio_net: enable napi for all possible queues during openJason Wang2013-05-231-4/+5
| | | | | | | | | | | | | | | Commit 55257d72bd1c51f25106350f4983ec19f62ed1fa (virtio-net: fill only rx queues which are being used) only does the napi enabling during open for curr_queue_pairs. This will break multiqueue receiving since napi of new queues were still disabled after changing the number of queues. This patch fixes this by enabling napi for all possible queues during open.

* tcp: bug fix in proportional rate reduction.Nandita Dukkipati2013-05-231-10/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a fix for a bug triggering newly_acked_sacked < 0 in tcp_ack(.). The bug is triggered by sacked_out decreasing relative to prior_sacked, but packets_out remaining the same as pior_packets. This is because the snapshot of prior_packets is taken after tcp_sacktag_write_queue() while prior_sacked is captured before tcp_sacktag_write_queue(). The problem is: tcp_sacktag_write_queue (tcp_match_skb_to_sack() -> tcp_fragment) adjusts the pcount for packets_out and sacked_out (MSS change or other reason). As a result, this delta in pcount is reflected in (prior_sacked - sacked_out) but not in (prior_packets - packets_out). This patch does the following: 1) initializes prior_packets at the start of tcp_ack() so as to capture the delta in packets_out created by tcp_fragment. 2) introduces a new "previous_packets_out" variable that snapshots packets_out right before tcp_clean_rtx_queue, so pkts_acked can be correctly computed as before. 3) Computes pkts_acked using previous_packets_out, and computes newly_acked_sacked using prior_packets.

* | tg3: Ensure boot code has completed initialization before accessing hardwareNithin Sujir2013-05-221-4/+4
|/ | | | | | | | | | | | | | | | | After resetting the device, the driver waits for a signature to be updated to know that firmware has completed initialization. However, the call to tg3_poll_fw() is being done too late and we're writing to the GRC_MODE register before it has completely initialized, causing contention with firmware. This logic has existed since day one but is causing PCIE link to go down randomly at startup on one platform once every few hundred reboots. Move the tg3_poll_fw() up to before we write to the GRC_MODE register after reset.

And for the iwlwifi bits, he says: "I have fixes for a firmware crash during resume, multicast RX, aggregation and a workaround for a firmware scanning bug." Along with those... Albert Pool adds a USB ID to the rtl8192cu driver. Arend van Spriel restores a driver option support flag that had been removed from 3.9 due to a bug in that version of the driver. Felix Fietkau fixes a trio of ath9k issues with a series of small patches. Geert Uytterhoeven provides a Kconfig fix for ath9k (which you also merged, so it isn't in the diff here). Larry Finger gives us a fix for a build warning on big-endian systems for rtlwifi. Rafał Miłecki adds some core IDs to the bcma driver. Sujith Manoharan fixes a module unloading crash in ath9k, and corrects some calibration settings for AR9485. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | * iwlwifi: mvm: fix aggregation drain flowEmmanuel Grumbach2013-05-165-18/+48

It is needed for the drain flow which happens once the ieee80211_sta has been freed, so keeping it in iwl_mvm_sta which is embed into ieee80211_sta is not a good idea. Also, since its purpose it to remove the STA in the fw only after all the frames for this station have exited the shared Tx queues, we need to decrement it in the reclaim flow. This flow can happen after ieee80211_sta has been removed, which means that we have no iwl_mvm_sta there. So we can't know what is the vif type. Hence, we know audit these frames for all the vif types. In order to avoid spawning sta_drained_wk all the time, we now check that we are in a flow in which draining might happen - only when mvmsta is NULL. This is better than previous code that would spawn sta_drained_wk all the time in AP mode.

The exception is fw restart flow when resuming from suspend when WoWLAN is enabled. In this case successive "add" and "modify" MAC_CONTEXT_CMD commands may be sent with assoc flag set what cause FW mal functioning. To prevent this never set assoc flag in MAC_CONTEXT_CMD with action "add".

The only possible interpretation is that the previous secondary channel offset remains valid, so use that when switching channel based only on beacon information. VHT requires the Wide Bandwidth Channel Switch subelement to be present in the Channel Switch Wrapper element, so the code for that is probably ok (see 802.11ac Draft 4, 8.4.2.165.)
