sfc: get PIO buffer size from the NIC
The 8000 series SFC NICs have 4K PIO buffers, rather than the 2K of the 7000 series. Rather than having a hard-coded PIO buffer size (ER_DZ_TX_PIOBUF_SIZE), read it from the GET_CAPABILITIES_V2 MCDI response. Signed-off-by: Edward Cree <ecree@solarflare.com> Signed-off-by: David S.
