* | qed*: Support other classification modes.Manish Chopra2018-05-252-2/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, driver supports flow classification to PF receive queues based on TCP/UDP 4 tuples [src_ip, dst_ip, src_port, dst_port] only. This patch enables to configure different flow profiles [For example - only UDP dest port or src_ip based] on the adapter so that classification can be done according to just those fields as well. Although, at a time just one type of flow configuration is supported due to limited number of flow profiles available on the device. For example - ethtool -N enp7s0f0 flow-type udp4 dst-port 45762 action 2 ethtool -N enp7s0f0 flow-type tcp4 src-ip 192.16.4.10 action 1 ethtool -N enp7s0f0 flow-type udp6 dst-port 45762 action 3 Signed-off-by: Manish Chopra <manish.chopra@cavium.com> Signed-off-by: Shahed Shaikh <shahed.shaikh@cavium.com> Signed-off-by: Ariel Elior <ariel.elior@cavium.com> Signed-off-by: David S.

* | qede: Add build_skb() support.Manish Chopra2018-05-174-174/+137

With this, driver can build skb directly from the page segments which are already mapped to the hardware instead of allocating new SKB via netdev_alloc_skb() and memcpy the data which is quite costly. This really improves performance (keeping same or slight gain in rx throughput) in terms of CPU utilization which is significantly reduced [almost half] in non HW gro flow where for every incoming MTU sized packet driver had to allocate skb, memcpy headers etc. Additionally in that flow, it also gets rid of bunch of additional overheads [eth_get_headlen() etc.] to split headers and data in the skb.

The patch defines a set of bit-fields for modes which are derived according to the mode info shared by the MFW and all the configuration would be made according to those. To add a new mode, there would be a single place where we'll need to go and choose which bits apply and which don't.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There may be a need for VF driver to request PF to explicitly update its bulletin with a MAC address. e.g. When user assigns a MAC address to VF while VF is still down, and PF's bulletin board contains different MAC address, in this case, when VF's interface is brought up, it gets loaded with MAC address from bulletin board which is not desirable.

| * | qede: Fix barrier usage after tx doorbell write.Manish Chopra2018-03-271-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit c5ad119fb6c09b0297446be05bd66602fa564758 ("net: sched: pfifo_fast use skb_array") driver is exposed to an issue where it is hitting NULL skbs while handling TX completions. Driver uses mmiowb() to flush the writes to the doorbell bar which is a write-combined bar, however on x86 mmiowb() does not flush the write combined buffer. This patch fixes this problem by replacing mmiowb() with wmb() after the write combined doorbell write so that writes are flushed and synchronized from more than one processor. V1->V2: ------- This patch was marked as "superseded" in patchwork. (Not really sure for what reason).Resending it as v2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Code includes wmb() followed by writel(). writel() already has a barrier on some architectures like arm64. This ends up CPU observing two barriers back to back before executing the register write. Create a new wrapper function with relaxed write operator.
