2012-09-30be2net: cleanup code related to be_link_status_query()Sathya Perla
1) link_status_query() is always called to query the link-speed (speed after applying qos). When there is no qos setting, link-speed is derived from port-speed. Do all this inside this routine and hide this from the callers. 2) adpater->phy.forced_port_speed is not being set anywhere after being initialized. Get rid of this variable. 3) Ignore async link_speed notifications till the initial value has been fetched from FW. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2012-09-30tg3: Disable multiple TX rings by default due to hardware flawMichael Chan
Simple round-robin hardware TX scheduling can cause starvation of TX rings with small packets when other TX rings have large TSO or jumbo packets. In the simplest case, consider 2 TCP streams running in opposite directions. The TSO TX traffic will hash to one ring and the ACKs for the incoming data on a different TCP connection will hash to a different TX ring. The hardware fetches one complete TSO packet (up to 64K data) before servicing the other TX ring. When it gets to the other TX ring, it will only fetch one packet (64-byte ACK packet in this case). After that, it will switch back to the 1st ring filled with more TSO packets. Because only one ACK can go out roughly every 500 usec in this case, the incoming data rate becomes very low. Update version to 3.125. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-09-27qlcnic: Fix scheduling while atomic bugNarendra K
In the device close path, 'qlcnic_fw_destroy_ctx' and 'qlcnic_poll_rsp' call msleep. But 'qlcnic_fw_destroy_ctx' and 'qlcnic_poll_rsp' are called with 'adapter->tx_clean_lock' spin lock held resulting in scheduling while atomic bug causing the following trace. I observed that the commit 012dc19a45b2b9cc2ebd14aaa401cf782c2abba4 from John Fastabend addresses a similar issue in ixgbevf driver. Adopting the same approach used in the commit, this patch uses mdelay to address the issue.

2012-09-27cxgb4: Don't attempt to upgrade T4 firmware when cxgb4 will end up as a slaveVipul Pandya
This patch adds a new common code routine to upgrade an adapter's firmware. This routine handles all of the complexities of working with the the existing adapter firmware in order to quiesce the adapter and uP, etc. For an automatic upgrade it will send a HELLO command to check if cxgb4 want/can upgrade firmware, i.e. if cxgb4 is MASTER and has newer firmware that it wants to load and call the new common code routine t4_fw_upgrade. Note that it should not issue a RESET command after a successful firmware upgrade.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== Please pull this last(?) batch of fixes intended for 3.6... For the Bluetooth bits, Gustavo says this: "Here goes probably my last update to 3.6. It includes the two patches you were ok last week(from Andrzej Kaczmarek), those are critical ones, and two other fixes one for a system crash and the other for a missing lockdep annotation." The referenced fixes from Andrzej prevent attempts to configure devices that are powered-off. Along with the Bluetooth fixes, there are a couple of 802.11 fixes. Emmanuel Grumbach gives us an iwlwifi fix to prevent releasing an interrupt twice. Luis R. Rodriguez provides a fix for a possible circular lock dependency in the cfg80211 regulatory enforcement code. All of these have been in linux-next for a few days. I hope they are not too late to make the 3.6 release! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2012-09-24gianfar: Change default HW Tx queue scheduling modeClaudiu Manoil
This is primarily to address transmission timeout occurrences, when multiple H/W Tx queues are being used concurrently. Because in the priority scheduling mode the controller does not service the Tx queues equally (but in ascending index order), Tx timeouts are being triggered rightaway for a basic test with multiple simultaneous connections like: iperf -c <server_ip> -n 100M -P 8 resulting in kernel trace: NETDEV WATCHDOG: eth1 (fsl-gianfar): transmit queue <X> timed out ------------[ cut here ]------------ WARNING: at net/sched/sch_generic.c:255 ... and controller reset during intense traffic, and possibly further complications. This patch changes the default H/W Tx scheduling setting (TXSCHED) for multi-queue devices, from priority scheduling mode to a weighted round robin mode with equal weights for all H/W Tx queues, and addresses the issue above.

2012-09-24net: loopback: set default mtu to 64KEric Dumazet
loopback current mtu of 16436 bytes allows no more than 3 MSS TCP segments per frame, or 48 Kbytes. Changing mtu to 64K allows TCP stack to build large frames and significantly reduces stack overhead. Performance boost on bulk TCP transferts can be up to 30 %, partly because we now have one ACK message for two 64KB segments, and a lower probability of hitting /proc/sys/net/ipv4/tcp_reordering default limit.

2012-09-24phy/micrel: Implement support for KSZ8021Marek Vasut
The KSZ8021 PHY was previously caught by KS8051, which is not correct. This PHY needs additional setup if it is strapped for address 0. In such case an reserved bit must be written in the 0x16, "Operation Mode Strap Override" register. According to the KS8051 datasheet, that bit means "PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021. The issue where the ethernet controller (Freescale FEC) did not communicate with network is fixed by writing this bit as 1. Signed-off-by: Marek Vasut <marex@denx.de> Cc: David J.

2012-09-24ixgbevf: Return error on failure to enable VLANAlexander Duyck
With recent kernel changes we can now return errors on a failure to setup a VLAN filter. This patch takes advantage of that opportunity so that we can return either an EIO error in the case of a mailbox failure, or an EACCESS error in the case of being denied access to the VLAN filter table by the PF.
