[for-next v1 0/5] RDMA/ionic: add SRQ support and firmware assigned CQ and SRQ IDs

From: Abhijit Gangurde <abhijit.gangurde@amd.com>
Date: 2026-09-08 09:10:08
Also in: linux-rdma, lkml

This series adds ionic Shared Receive Queue support and lets firmware assign
CQ/SRQ IDs when the LIF advertises qid-allocation capability.

Patch 1: extends the RDMA LIF identity with SRQ qtype and alloc_qid_cap.
Patch 2: uses that for firmware-assigned CQ IDs and splits CQ create/destroy
so cq_tbl is updated only after the ID is known, and removed before the ID
is returned to firmware.
Patches 3: Refactor RQ state into ionic_rq so QP RQ and SRQ share init/destroy.
Patches 4-5: add SRQ verbs and EQ events. Userspace ABI field srqid is new
with this series;
