Recent change in virtio_net_hdr_to_skb() broke some packetdrill tests.
When --mss=XXX option is set, packetdrill always provide gso_type & gso_size
for its inbound packets, regardless of packet size.
if (packet->tcp && packet->mss) {
if (packet->ipv4)
gso.gso_type = VIRTIO_NET_HDR_GSO_TCPV4;
else
gso.gso_type = VIRTIO_NET_HDR_GSO_TCPV6;
gso.gso_size = packet->mss;
}
Since many other programs could do the same, relax virtio_net_hdr_to_skb()
to no longer return an error, but instead ignore gso settings.
This keeps Willem intent to make sure no malicious packet could
reach gso stack.
Note that TCP stack has a special logic in tcp_set_skb_tso_segs()
to clear gso_size for small packets.

net: ks8851: Unify KS8851 SPI and MLL drivers
The KS8851SNL/SNLI and KS8851-16MLL/MLLI/MLLU are very much the same pieces
of silicon, except the former has an SPI interface, while the later has a
parallel bus interface. Thus far, Linux has two separate drivers for each
and they are diverging considerably.
This series unifies them into a single driver with small SPI and parallel
bus specific parts. The approach here is to first separate out the SPI
specific parts into a separate file, then add parallel bus accessors in
another separate file and then finally remove the old parallel bus driver.
The reason for replacing the old parallel bus driver is because the SPI
bus driver is much higher quality.
Note that I dropped "net: ks8851: Drop define debug and pr_fmt()" for now,
will send it separatelly later.

Implement accessors for KS8851-16MLL/MLLI/MLLU parallel bus variant of
the KS8851. This is based off the ks8851_mll.c , which is a driver for
exactly the same hardware, however the ks8851.c code is much higher
quality. Hence, this patch pulls out the relevant information from the
ks8851_mll.c on how to access the bus, but uses the common ks8851.c
code. To make this patch reviewable, instead of rewriting ks8851_mll.c,
ks8851_mll.c is removed in a separate subsequent patch.
