[PATCH v2 0/5] Pad all inbound frames to 802.3 minimum size if needed

[Stefano Brivio <sbrivio@redhat.com>]

Patch 1/5 handles the easy non-batched case with a copy to a padded
buffer (only if needed).

Patches 2/5 and 3/5 clean coding style up before further changes.

Patch 4/5 deals with TCP and UDP batched frames in non-vhost-user modes.

Patch 5/5 is for batched frames in vhost-user mode instead.

v2:
  * in 1/5, calculate vnet_len *after* padding
  * in 5/5:
    - pass the right pointers to memset()
    - explicitly request at least ETH_ZLEN bytes from vu_collect()

Stefano Brivio (5):
  tap: Pad non-batched frames to 802.3 minimum (60 bytes) if needed
  tcp: Fix coding style for comment to enum tcp_iov_parts
  udp: Fix coding style for comment to enum udp_iov_idx
  tcp, udp: Pad batched frames to 60 bytes (802.3 minimum) in
    non-vhost-user modes
  tcp, udp: Pad batched frames for vhost-user modes to 60 bytes (802.3
    minimum)
