When running RHEL6 userspace on a current upstream kernel, "ip link" fails to show VF information. The reason is a kernel<->userspace API change introduced by commit 88c5b5ce ("rtnetlink: Call nlmsg_parse() with correct header length"), after which the kernel does not see iproute2's IFLA_EXT_MASK attribute in the netlink request. iproute2 adjusted for the API change in its commit 63338dca4513 ("libnetlink: Use ifinfomsg instead of rtgenmsg in rtnl_wilddump_req_filter"). The problem has been noticed before: http://marc.info/?l=linux-netdev&m=136692296022182&w=2 (Subject: Re: getting VF link info seems to be broken in 3.9-rc8) We can do better than tell those with old userspace to upgrade. We can recognize the old iproute2 in the kernel by checking the netlink message length. Even when including the IFLA_EXT_MASK attribute, its netlink message is shorter than struct ifinfomsg. With this patch "ip link" shows VF information in both old and new iproute2 versions. Signed-off-by:

And imx6q/dl SOC FEC Gbps speed has HW bus Bandwidth limitation (400Mbps ~ 700Mbps), imx6sx SOC FEC Gbps speed has no HW bandwidth limitation. The patch set just enable TSO feature, which is done following the mv643xx_eth driver. Test result analyze: imx6dl sabresd board: there have 82% improvement, since imx6dl FEC HW has bandwidth limitation, the performance with SW TSO is a milestone. Addition test: imx6sx sdb board: upstream still don't support imx6sx due to some patches being upstream... they use same FEC IP. Use the SW TSO patches test imx6sx sdb board in internal kernel tree: No SW TSO patch: tx bandwidth 840Mbps, cpu loading is 100%. SW TSO patch: tx bandwidth 942Mbps, cpu loading is 65%. It means the patch set have great improvement for imx6sx FEC performance. V2: * From Frank Li's suggestion: Change the API "fec_enet_txdesc_entry_free" name to "fec_enet_get_free_txdesc_num". * Summary David Laight and Eric Dumazet's thoughts: RX BD entry number change to 256. * From ezequiel's suggestion: Follow the latest TSO fixes from his solution to rework the queue stop/wake-up. Avoid unmapping the TSO header buffers. * From Eric Dumazet's suggestion: Avoid more bytes copy, just copying the unaligned part of the payload into first descriptor. The suggestion will bring more complex for the driver, and imx6dl FEC DMA need 16 bytes alignment, but cpu loading is not problem that cpu loading is 30%, the current performance is so better. Later chip like imx6sx Gigbit FEC DMA support byte alignment, so there don't exist memory copy. So, the V2 version drop the suggestion. Anyway, thanks for Eric's response and suggestion. V3: * From David Laight's feedback: Decide to drop RX BD entry number change for the SW TSO patch set. I will generate one separate patch to increase RX BDs entry for interrupt coalescing feature which will be supported in my later patch set. V4: * From David Laight's feedback: Remove the conditional in .fec_enet_get_bd_index(). V5: * Patch #4 update: From David Laight's feedback: "expect fec_enet_get_free_txdesc_num() to return one less than it does currently." Change the function: Return space available, 0..size-1. it always leave one free entry. Which is same as linux circ_buf.

A malicious VF might try to starve the other VFs & PF by creating contineous doorbell floods. In order to negate this, HW has a threshold of doorbells per client, which will stop the client doorbells from arriving if crossed. The threshold currently configured for VFs is too low - under extreme traffic scenarios, it's possible for a VF to reach the threshold and thus for its fastpath to stop working. Signed-off-by:

This avoids clearing the RX polarity setting in KR mode when polarity lane is swapped, as otherwise this will result in failed link. Signed-off-by:

Consider the scenario: For a TCP-style socket, while processing the COOKIE_ECHO chunk in sctp_sf_do_5_1D_ce(), after it has passed a series of sanity check, a new association would be created in sctp_unpack_cookie(), but afterwards, some processing maybe failed, and sctp_association_free() will be called to free the previously allocated association, in sctp_association_free(), sk_ack_backlog value is decremented for this socket, since the initial value for sk_ack_backlog is 0, after the decrement, it will be 65535, a wrap-around problem happens, and if we want to establish new associations afterward in the same socket, ABORT would be triggered since sctp deem the accept queue as full. Fix this issue by only decrementing sk_ack_backlog for associations in the endpoint's list. Fix-suggested-by:

These defconfigs contain the CONFIG_M25P80 symbol, which is now dependent on the MTD_SPI_NOR symbol. Add CONFIG_MTD_SPI_NOR to the relevant defconfigs. At the same time, drop the now-nonexistent CONFIG_MTD_CHAR symbol. Signed-off-by:

We have a number of front-end drivers for SDHCI_PLTFM, some of them use 'select MMC_SDHCI_PLTFM', others use 'depends on'. This is inconsistent and confusing, and in one case has also led to a build error because of incomplete dependencies: warning: (MMC_SDHCI_PXAV3 && MMC_SDHCI_PXAV2 && MMC_SDHCI_BCM_KONA) selects MMC_SDHCI_PLTFM which has unmet direct dependencies (MMC && MMC_SDHCI) drivers/built-in.o: In function `sdhci_sirf_resume': :(.text+0xaaacb4): undefined reference to `sdhci_resume_host' drivers/built-in.o: In function `sdhci_sirf_suspend': :(.text+0xaaacf8): undefined reference to `sdhci_suspend_host' drivers/built-in.o: In function `sdhci_sirf_probe': :(.text+0xaaaf44): undefined reference to `sdhci_add_host' :(.text+0xaaaf50): undefined reference to `sdhci_remove_host' This changes Kconfig to use 'depends on MMC_SDHCI_PLTFM' for all these cases, to fix the build error and make the logic more logical.
