As shown by Dmitris, we need to use csum_block_add() instead of csum_add()
when adding the FCS contribution to skb csum.
Before 4.18 (more exactly commit 88078d98d1bb "net: pskb_trim_rcsum()
and CHECKSUM_COMPLETE are friends"), the whole skb csum was thrown away,
so RXFCS changes were ignored.

When hns3_get_ring_config()/hns3_queue_to_ring()/
hns3_get_vector_ring_chain() failed during resetting, the allocated

The limit for memory locked in the kernel by a process is usually set to

Extends the existing udp programs to allow checking for proper
GRO aggregation/GSO size, and run the tests via a shell script, using
a veth pair with XDP program attached to trigger the GRO code path.
rfc v2 -> rfc v3:
- add missing test program options documentation
- fix sporatic test
XDP support will be used by a later patch to test the GRO path
in a net namespace, leveraging the veth XDP implementation.
To avoid breaking existing setup, XDP support is conditionally
enabled and build only if llc is locally available.
rfc v2 -> rfc v3:
- move 'x' option handling here
And fix a couple of buglets (port option processing,
clean termination on SIGINT). This is preparatory work
for GRO tests.

- use ETH_MAX_MTU
