Subject: [PATCH 5.16 0480/1039] RDMA/qedr: Fix reporting max_{send/recv}_wr attrs
From: Kamal Heib <kamalheib1@...il.com>
[ Upstream commit b1a4da64bfc189510e08df1ccb1c589e667dc7a3 ]
Fix the wrongly reported max_send_wr and max_recv_wr attributes for user
QP by making sure to save their valuse on QP creation, so when query QP is
called the attributes will be reported correctly.
Fixes: cecbcddf6461 ("qedr: Add support for QP verbs")
