c6845644cc net/sfc: support per-queue Rx prefix for EF100
Riverhead FW supports Rx prefix choice based on required fields in Rx
prefix. The feature is generalized in libefx to provide Rx prefixes
layout for other NICs and firmware variants. Now driver can get
the prefix layout after Rx queue start and use the layout details to
check its expectations or simply in run-time.

Rx prefix choice and query interface is defined in SF-119689-TC
EF100 host interface.

38109b5b08 net/sfc: add header segments check for EF100 Tx
EF100 native Tx datapath demands that packet header be contiguous
when partial checksum offloads are used since helper function is
used to calculate pseudo-header checksum (and the function requires
contiguous header).

Add an explicit check for this assumption and restructure the code
to avoid TSO header linearisation check since TSO header
linearisation is not done on EF100 native Tx datapath.

53a73b7b9d net/af_xdp: forbid umem sharing for xsks with same context
AF_XDP PMDs who wish to share a UMEM must have a unique context
(ctx) ie. netdev,qid tuple. For instance, the following will not
work since both PMDs' contexts are identical.

  --vdev net_af_xdp0,iface=ens786f1,start_queue=0,shared_umem=1
  --vdev net_af_xdp1,iface=ens786f1,start_queue=0,shared_umem=1

Supporting this scenario would require locks, which would impact
the performance of the more typical cases - xsks with different
netdev,qid tuples.

Later this ring freed in the '.dev_close' dev_ops.

If the 'infinite_rx' provided and '.dev_close' called before
'.rx_queue_setup', the ring will be NULL and trying to empty/free it

This is fixed by adding ring NULL check before trying to empty/free it.
