net/mlx5e: Permit XDP with non-linear legacy RQ
Now that legacy RQ implements XDP in the non-linear mode, stop blocking
this configuration. Allow non-linear mode only for programs aware of
multi buffer.
XDP performance with linear mode RQ hasn't changed.
Baseline (MTU 1500, TX MPWQE, legacy RQ, single core):
60-byte packets, XDP_DROP: 11.25 Mpps
60-byte packets, XDP_TX: 9.0 Mpps
60-byte packets, XDP_PASS: 668 kpps
Multi buffer (MTU 9000, TX MPWQE, legacy RQ, single core):
60-byte packets, XDP_DROP: 10.1 Mpps
60-byte packets, XDP_TX: 6.6 Mpps
60-byte packets, XDP_PASS: 658 kpps
8900-byte packets, XDP_DROP: 769 kpps (100% of sent packets)
8900-byte packets, XDP_TX: 674 kpps (100% of sent packets)
8900-byte packets, XDP_PASS: 637 kpps
