Subject: r8152: fix the sw rx checksum is unavailable
From: hayeswang <hayeswang@xxxxxxxxxxx>
[ Upstream commit 19c0f40d4fca3a47b8f784a627f0467f0138ccc8 ]
Fix the hw rx checksum is always enabled, and the user couldn't switch
it to sw rx checksum.
Note that the RTL_VER_01 only support sw rx checksum only. Besides,
the hw rx checksum for RTL_VER_02 is disabled after
commit b9a321b48af4 ("r8152: Fix broken RX checksums."). Re-enable it.
