The ks8995 phy driver just started using gpiod_* functions, which are declared in linux/gpio/consumer.h, not linux/gpio.h, resulting in a build failure in randconfig builds that do not have CONFIG_GPIOLIB enabled: drivers/net/phy/spi_ks8995.c: In function 'ks8995_probe': drivers/net/phy/spi_ks8995.c:477:3: error: implicit declaration of function 'gpiod_set_value' [-Werror=implicit-function-declaration] This changes the header inclusion so it builds in all configurations.

There are several scenarios where taking a register dump from a device might log benign GRC timeout attentions to system logs. Most common of those is when taking the dump from a 2-port device. Sadly, there's no easy way to mask the problematic attentions during the flow - Changing this behvaior would require a firmware update. For now, simply warn users to ignore the warnings.

Driver is currently looking at shared information for determining whether DCBx can be supported for a given port. On 4-port devices, up-to-date management firmware can support DCBx on each port of a given engine independently - but that would cause bnx2x to misinterpert the support and assume DCBx is supported on both.

由 Amitoj Kaur Chawla 提交于
This change has been made with the goal that kernel functions should return something more descriptive than -1 on failure. A variable `err` has been introduced for storing error codes. The return value of kzalloc on failure should return a -1 and not a -ENOMEM. This was found using Coccinelle. A simplified version of the semantic patch used is: //<smpl> @@ expression *e; identifier l1; @@ e = kzalloc(...); if (e == NULL) { ... goto l1; } l1: ... return -1 + -ENOMEM ; //</smpl Furthermore, set `err` to -ENOMEM on failure of alloc_netdev(), and to -ENODEV on failure of register_netdev() and probe_irq_off(). The single call site only checks that the return value is not 0, hence no change is required at the call site. Signed-off-by: NAmitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: NDavid S.

由 Alexander Duyck 提交于
There was a workaround partially implemented for the 82576 that is needed in order for VLAN tag stripping to function correctly. The original code had side effects that would make it so the workaround was active on all MACs. I have updated the code so that the workaround is enabled, but limited to the 82576, or activated if we exceed the available unicast addresses. The workaround has a side effect of mirroring all of the traffic outgoing from the VFs back to the PF. As such it is not recommended to use the 82576 in promiscuous mode as it will take a performance hit, though this is now consistent with the performance as seen on the out-of-tree igb driver. I also limited the scope of the UTA bits all being set to only when the VMOLR register is enabled. This should limit the effects of the UTA register so that we don't pick up any excess traffic unless promiscuous mode has been enabled on the PF, whereas before the PF would have ended up in something equivalent to unicast promiscuous mode with VLAN filtering otherwise.

This change makes it so that we can use the bridge utility to add a FDB entry for the PF to an igb port. By doing this we can enable the VFs to talk to virtual ports residing on top of the PF. In addition this should also address issues with MACVLANs trying to reside on top of the PF as well as they would have had similar issues when added to the PF with SR-IOV enabled.

This patch is meant to clean-up the configuration of the VF port based VLAN configuration. The original logic was a bit muddled and had some undesirable side effects such as VLANs being either completely stripped from the port or VLANs being left when they shouldn't be. The idea behind this code is to avoid any events such as spurious spoof notifications when we are removing one VLAN tag and replacing it with another.

Since the igb driver is using page based receive there is no point in limiting the Rx capabilities of the device. The driver can receive 9K jumbo frames at all times. The only changes needed due to MTU changes are updates for the FIFO sizes and flow-control watermarks. Update the maximum frame size to reflect the 9.5K limitation of the hardware, and replace all instances of max_frame_size with MAX_JUMBO_FRAME_SIZE when referring to an Rx FIFO or frame.
