Subject: tg3: Do not enable APE on bcm5700
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b2b98d4acc58a6f36b731e666c6ebd901cd6a27e;p=linux-beck.git

tg3: Do not enable APE on bcm5700

With older versions of the NVRAM format, the driver may mistakenly
determine that APE is enabled.  Make sure this doesn't happen by
restricting the ENABLE_APE check to devices known to have more
recent NVRAM image formats.
