[net-next,0/3] gve: Add jumbo-frame support for GQ

Message

This patchset introduces jumbo-frame support for the GQ queue format.
The device already supports jumbo-frames on TX. This introduces
multi-descriptor RX packets using a packet continuation bit.

A widely deployed driver has a bug with causes it to fail to load
when a MTU greater than 2048 bytes is configured. A jumbo-frame device
option is introduced to pass a jumbo-frame MTU only to drivers that
support it.

  gve: Add RX context.
  gve: Implement packet continuation for RX.

Shailend Chand (1):
  gve: Add a jumbo-frame device option.
