From: Auke Kok Date: Wed, 31 Oct 2007 22:22:10 +0000 (-0700) Subject: ixgbe: Fix copper PHY initialization code X-Git-Tag: firefly_0821_release~23655^2~623 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3957d63da0067ad6a7dc8261b7eeb824f9dc42b4;p=firefly-linux-kernel-4.4.55.git ixgbe: Fix copper PHY initialization code While cleaning up the internal API focussing on Fiber and CX4 code we found that I had broken the copper PHY initialization code. This patch restores the PHY-specific code. This is mostly uninteresting since no copper PHY boards are yet available. The changes have been tested against Fiber only as I do not even have copper PHY versions of 82598 macs. This change actually cleans up the API code a bit more and we lose some initialization code. A few PHY link detection helper lines of code have been snuck into this patch, as well as a read flush where it was suspected that this might cause issues.
