Subject: [dpdk-stable] [PATCH v2 03/20] net/ixgbe/base: fix host interface shadow RAM read
Date: Thu, 2 Jul 2020 03:13:12 +0000 [thread overview]
Message-ID: <20200702031329.4495-4-guinanx.sun@intel.com> (raw)
In-Reply-To: <20200702031329.4495-1-guinanx.sun@intel.com>
Host interface Shadow RAM Read (0x31) command response
buffer length should be stored in two bytes, instead of one byte.
This patch fixes it.
Fixes: e6102361b1d4 ("net/ixgbe/base: use 2 bytes for flash read command")
