MFW requests the TLVs in interrupt context. Extracting of the required data from upper layers and populating of the TLVs require process context. The patch adds work-queues for processing the tlv requests. It also adds the implementation for requesting the tlv values from appropriate protocol driver. Signed-off-by:

The patch adds driver support for processing TLV requests/repsonses from the mfw and upper driver layers respectively. The implementation reads the requested TLVs from the shared memory, requests the values from upper layer drivers, populates this info (TLVs) shared memory and notifies MFW about the TLV values.

This patch makes use of build_skb() throughout in driver's receieve data path [HW gro flow and non HW gro flow]. 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. Tested with: system: 2 sockets, 4 cores per socket, hyperthreading, 2x4x2=16 cores iperf [server]: iperf -s iperf [client]: iperf -c <server_ip> -t 500 -i 10 -P 32 HW GRO off – w/o build_skb(), throughput: 36.8 Gbits/sec Average: CPU %usr %nice %sys %iowait %irq %soft %steal %guest %idle Average: all 0.59 0.00 32.93 0.00 0.00 43.07 0.00 0.00 23.42 HW GRO off - with build_skb(), throughput: 36.9 Gbits/sec Average: CPU %usr %nice %sys %iowait %irq %soft %steal %guest %idle Average: all 0.70 0.00 31.70 0.00 0.00 25.68 0.00 0.00 41.92 HW GRO on - w/o build_skb(), throughput: 36.9 Gbits/sec Average: CPU %usr %nice %sys %iowait %irq %soft %steal %guest %idle Average: all 0.86 0.00 24.14 0.00 0.00 6.59 0.00 0.00 68.41 HW GRO on - with build_skb(), throughput: 37.5 Gbits/sec Average: CPU %usr %nice %sys %iowait %irq %soft %steal %guest %idle Average: all 0.87 0.00 23.75 0.00 0.00 6.19 0.00 0.00 69.19 Signed-off-by:

Stress on qedi/qedr load unload lead to list_del corruption. This is due to ll2 connection terminate freeing resources without verifying that no more ll2 processing will occur.

This patch adds driver changes for supporting the Unified Fabric Port (UFP). This is a new paritioning mode wherein MFW provides the set of parameters to be used by the device such as traffic class, outer-vlan tag value, priority type etc. Drivers receives this info via notifications from mfw and configures the hardware accordingly.

`mf_mode' field indicates the multi-partitioning mode the device is configured to. This method doesn't scale very well, adding a new MF mode requires going over all the existing conditions, and deciding whether those are needed for the new mode or not. 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. Signed-off-by:

The strscpy() was a recent fix (net: qed: use correct strncpy() size) to prevent passing the length of the source buffer to strncpy() and guarantee null termination. It misses the goal of overwriting only the first 3 characters in "???_BIG_RAM" and "???_RAM" while keeping the rest of the string. Use strncpy() with the length of 3, without null termination.

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. To handle this corner case, we need a new TLV to request PF to update its bulletin board with suggested MAC. This request will be honored only for trusted VFs. Signed-off-by:

As per existing behavior, when PF sets a MAC address for a VF (also called as forced MAC), VF is not allowed to change its MAC address afterwards. This puts the limitation on few use cases such as bonding of VFs, where bonding driver asks VF to change its MAC address. This patch uses a VF trust mode to allow VF to change its MAC address in spite PF has set a forced MAC for that VF. Signed-off-by:

Since commit c5ad119f ("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. Signed-off-by:

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.
