Subject: r8169: remove mii_if_info member from struct rtl8169_private
X-Git-Tag: v4.19-rc1~140^2~343^2~1
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=f7ffa9ae2bb90fd948b514e2049ef3a904e66743;p=linux.git

r8169: remove mii_if_info member from struct rtl8169_private

The only remaining usage of the struct mii_if_info member is to store the
information whether the chip is GMII-capable. So we can replace it with
a simple flag.
