Details

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 efxseparatetx_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 efxchannelhastxqueues to return the correct value for this case too.
