Subject: [PATCH v4] net/i40e: fix max frame size config at port level
Date: Wed, 18 May 2022 04:49:02 +0000	[thread overview]
Message-ID: <20220518044902.270700-1-wenxuanx.wu@intel.com> (raw)
In-Reply-To: <20220513072049.149333-1-wenxuanx.wu@intel.com>

From: Wenxuan Wu <wenxuanx.wu@intel.com>

Previously, max frame size can only be set when link is up, and the wait
time is 1 sec. Startup time of 10G_BASET longer than 1s would result in
failure.

Acctually, max frame size of media type I40E_MEDIA_TYPE_BASET can be set
regardless of link status.

This patch omitted the link status check of 10G_MEDIA_TYPE_BASET.

Fixes: a4ba77367923 ("net/i40e: enable maximum frame size at port level")
Cc: stable@dpdk.org
