| * | | | | bnx2x: Take chip version from MFWYuval Mintz2013-03-122-6/+8

| * | | | | bnx2x: Set ethtool ops for vfsAriel Elior2013-03-123-4/+29

Instead of checking in each op whether the device being driven is a virtual function or a physical function, this patch creates a separate ethtool ops struct for virtual functions and uses it to initialize the ethtool ops of the driver in case it is driving a virtual function device.

During the manipulation required to release those resources, it's possible for the UNDI to try and write to memory regions which are no longer accessible, causing the PCI bus to prevent further writes from the chip. This would in turn cause DMAE timeouts later on in the driver, as the driver will be unable to use the chip's DMA engines. This patch prevents the chip from actually writing through the PCI bus in said scenario, thus allowing the release without the unfortunate by-product.

One such struct is the queue object for the FCoE queue. If a device is working in AFEX mode and its configuration allows FCoE yet the cnic module is not loaded, it's very likely a null pointer dereference will occur, as the bnx2x will erroneously access the FCoE's queue object. Prevent said access until cnic properly registers itself.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | When a KR2 device is connected to a KR link-partner, sometimes it requires disabling KR2 for the link to come up. To get a KR2 link up later, in case no base pages are seen, the KR2 is restored. The problem was that some link partners cleared their advertised BP/NP after around two seconds, causing the driver to disable/enable KR2 link all the time. The fix was to wait at least 5 seconds before checking KR2 recovery. Signed-off-by: Yaniv Rosner <yanivr@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

When the VF samples the Bulletin Board it copies the message aside and validates this crc. The length of the message is crucial here and must be the same in both parties. Since the PF is running in the Hypervisor and the VF is running in a Vm, they can possibly be of different versions. As the Bulletin Board is designed to grow forward in future versions, in the VF the length must not be the size of the message structure but instead it should be a field in the message itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In INTA mode, cnic and bnx2x share the same IRQ. During chip reset, for example, cnic will stop servicing IRQs after it has shutdown the cnic hardware resources. However, the shared IRQ is still active as bnx2x needs to finish the reset. There is a window when bnx2x does not know that cnic is no longer handling IRQ and things don't always work properly. Add a flag to tell bnx2x that cnic is handling IRQ. The flag is set before the first cnic IRQ is expected and cleared when no more cnic IRQs are expected, so there should be no race conditions.

Return values after if-else instead of only on the else condition (where current flow would simply return same value later in the code) 4.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since submit 621b4d6 the bnx2x driver support FW GRO. However, when using the device with GRO enabled in bridging scenarios throughput is very low, as the bridge expects all incoming packets to be passed with CHECKSUM_PARTIAL - a demand which is satisfied by the SW GRO implementation, but was missed in the bnx2x driver implementation (which returned CHECKSUM_UNNECESSARY). Now, given that the traffic is supported by FW GRO (TCP/IP), the bnx2x driver calculates the pseudo checksum by itself, passing skbs with CHECKSUM_PARTIAL and giving a much better throughput when receiving GRO traffic.
