Subject: [Intel-wired-lan] [PATCH 1/2] net: intel: igb: minor ethool regdump amendment
Date: Tue, 18 Jun 2019 14:55:12 +0300	[thread overview]
Message-ID: <20190618115513.99661-1-dedekind1@gmail.com> (raw)

From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

This patch has no functional impact and it is just a preparation
for the following patch. It removes an early return from the
'igb_get_regs()' function by moving the 82576-only registers
dump into an "if" block. With this preparation, we can dump more
non-82576 registers at the end of this function.
