Subject: [PATCH v3 06/18] net/bnxt: support backward compatibility
Date: Tue, 26 Dec 2023 20:21:07 -0800 [thread overview]
Message-ID: <20231227042119.72469-7-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20231227042119.72469-1-ajit.khaparde@broadcom.com>

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
On older firmware versions, HWRM_FUNC_QCAPS response is not
returning the maximum number of multicast filters that can be
supported by the function. As a result, memory allocation with
size 0 fails.
Bugzilla ID: 1309
