Create a core TX queue and 2 hardware TX queues for each channel. If separate_tx_channels is set, create equal numbers of RX and TX channels instead. Rewrite the channel and queue iteration macros accordingly. Eliminate efx_channel::used_flags as redundant. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.
