Subject: [dpdk-dev] [PATCH v3 07/16] net/bnxt: fix L2 context calculation for Thor
Date: Wed,  2 Oct 2019 10:17:36 -0700	[thread overview]
Message-ID: <20191002171745.4504-8-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20191002171745.4504-1-ajit.khaparde@broadcom.com>

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

On Wh+, number of L2 context supported by FW is the sum of number of
EM flow count and number of L2 context count returned in HWRM_FUNC_QCFG.
This is not true for Thor. Restrict this only for Whitney for now.

Fixes: ff9c0ca47e81176 ("net/bnxt: save the number of EM flow count")
