Subject: [PATCH rdma-next 00/10] RDMA/bnxt_re: Add receive flow steering support

Hi,

The RDMA stack allows for applications to create IB_QPT_RAW_PACKET
QPs, which receive plain Ethernet packets. This patch adds ib_create_flow()
and ib_destroy_flow() support in the bnxt_re driver. For now, only the
sniffer rule is supported to receive all port traffic. This is to support
tcpdump over the RDMA devices to capture the packets.

Patch#1 is Ethernet driver change to reserve more stats context to RDMA device.
Patch#2, #3 and #4 are code refactoring changes in preparation for subsequent patches.
Patch#5 adds support for unique GID.
Patch#6 adds support for mirror vnic.
Patch#7 adds support for flow create/destroy.
Patch#8 enables the feature by initializing FW with roce_mirror support.
Patch#9 is to improve the timeout value for the commands by using firmware provided message timeout value.
Patch#10 is another related cleanup patch to remove unnecessary checks.

This patch series is created on top of the below series posted on 08/14/2025:
