tg3: Fix io failures after chip reset
BugLink: http://bugs.launchpad.net/bugs/868628
commit 9e975cc291d80d5e4562d6bed15ec171e896d69b upstream.
Commit f2096f94b514d88593355995d5dd276961e88af1, entitled
"tg3: Add 5720 H2BMC support", needed to add code to preserve some bits
set by firmware. Unfortunately the new code causes throughput to stop
after a chip reset because it enables state machines before they are
ready. This patch undoes the problematic code. The bits will be
restored later in the init sequence.
