Hi,
about nine months ago, Jan (Kara, SUSE) reported a throughput
regression with BFQ. That was the beginning of a fruitful dev&testing
collaboration, which led to 18 new commits. Part are fixes, part are
actual performance improvements.

Commit 9fd1ff5d2ac7 ("udp: Support UDP fraglist GRO/GSO.") actually
not only added a support for fraglisted UDP GRO, but also tweaked
some logics the way that non-fraglisted UDP GRO started to work for
forwarding too.

Introduce a new netdev feature, NETIF_F_GRO_UDP_FWD, to allow user

Once a port is created, the application can mmap the corresponding DMA
