In the Linux kernel, the following vulnerability has been resolved: sfc: fix considering that all channels have TX queues Normally, all channels have RX and TX queues, but this is not true if modparam efx_separate_tx_channels=1 is used. In that cases, some channels only have RX queues and others only TX queues (or more preciselly, they have them allocated, but not initialized). Fix efx_channel_has_tx_queues to return the correct value for this case too.
