Hello netdev team,

Here is a respin of the previous PR, after gathering an extra review
from sashiko. This PR also includes an extra fix for the selftests.

Patch 1 is ensuring that the MAC header offset is reset before
deliering the packet to the upper layer. Not doing so could trick other
parts of the networking stack into wrong calculations.

Patch 1 fixes the inconsistent call context for gro_cells_receive() and
dev_dstats_rx_add().
On a TCP connection, we can end up calling gro_cells_receive() from
process context, which is unexpected (and could potentially trigger
deadlocks). At the same time, also dev_dstats_rx_add() should not be
invoked concurrently on the same CPU (i.e. from a softirq).
For this reason we're wrapping the aforementioned calls within
local_bh_disable/enable().


Ideally all selftests should always succeed now.

Please pull or let me know of any issue.

Thanks,
	Antonio
