Subject: [PATCH net-next 0/6] AF_XDP infrastructure improvements

This series contains improvements to the AF_XDP kernel infrastructure.
They are required for the upcoming AF_XDP support in mlx5e, but also
some of them benefit to all drivers, and some can be useful for other
drivers that want to implement AF_XDP.

Maxim Mikityanskiy (6):
  samples/bpf: Add hbm to .gitignore
  xsk: Add API to check for available entries in FQ
  xsk: Add getsockopt XDP_OPTIONS
  xsk: Extend channels to support combined XSK/non-XSK traffic
  xsk: Change the default frame size to 4096 and allow controlling it
  xsk: Return the whole xdp_desc from xsk_umem_consume_tx
