Subject: [PATCH 2/4] net/bnxt: fix QP resource count in backing store config
Date: Wed,  3 Jun 2026 11:51:35 -0600	[thread overview]
Message-ID: <20260603175137.1990204-3-Mohammad-Shuab.Siddique@broadcom.com> (raw)
In-Reply-To: <20260603175137.1990204-1-Mohammad-Shuab.Siddique@broadcom.com>

From: Ajit Khaparde <ajit.khaparde@broadcom.com>

The driver is not passing the QP1 count while
configuring backing store for QP type.
This can result in a smaller set of entries allocated by the
driver with the firmware.

The number of entries is provided by the firmware as a
part of backing store qcaps v2 HWRM command.

Fixes: 5b5d398434f9 ("net/bnxt: add support for backing store v2")
