Subject: [PATCH 1/1] RDMA/efa: Set maximum pkeys device attribute
Git-commit: 0133654d8eb8607eacc96badfe49bf992155f4cb
Patch-mainline: v5.8-rc3
References: bsc#1111666

The max_pkeys device attribute was not set in query device verb, set it to
one in order to account for the default pkey (0xffff). This information is
exposed to userspace and can cause malfunction

Fixes: 40909f664d27 ("RDMA/efa: Add EFA verbs implementation")
