Subject: [PATCH net-next 3/8] i40e: use minimal Rx and Tx ring buffers for kdump
Date: Fri, 23 Apr 2021 09:42:42 -0700 [thread overview]
Message-ID: <20210423164247.3252913-4-anthony.l.nguyen@intel.com> (raw)
In-Reply-To: <20210423164247.3252913-1-anthony.l.nguyen@intel.com>
From: Coiby Xu <coxu@redhat.com>
Use the minimum of the number of descriptors thus we will allocate the
minimal ring buffers for kdump.
