Subject: virtio-net: alloc big buffers also when guest can receive UFO
From: Jason Wang <[email protected]>
[ Upstream commit 0e7ede80d929ff0f830c44a543daa1acd590c749 ]
We should alloc big buffers also when guest can receive UFO
packets to let the big packets fit into guest rx buffer.
Fixes 5c5167515d80f78f6bb538492c423adcae31ad65
(virtio-net: Allow UFO feature to be set and advertised.)
