Subject: [PATCH 4/6] lpfc: Add 256Gb link speed support
Date: Thu, 22 Jul 2021 15:17:19 -0700	[thread overview]
Message-ID: <20210722221721.74388-5-jsmart2021@gmail.com> (raw)
In-Reply-To: <20210722221721.74388-1-jsmart2021@gmail.com>

Update routines to support 256Gb link speed for LPe37000/LPe38000
adapters. 256Gb speeds can be seen on trunk links.
