Subject: [PATCH 5.10 080/167] bnxt_en: Refresh RoCE capabilities in bnxt_ulp_probe()

From: Michael Chan <michael.chan@...adcom.com>

[ Upstream commit 2c9f046bc377efd1f5e26e74817d5f96e9506c86 ]

The capabilities can change after firmware upgrade/downgrade, so we
should get the up-to-date RoCE capabilities everytime bnxt_ulp_probe()
is called.

Fixes: 2151fe0830fd ("bnxt_en: Handle RESET_NOTIFY async event from firmware.")
