net: ti: icssg-prueth: Add functions to create and destroy Rx/Tx queues

Browse source

Each port for a given ICSSG instance has their own set of
Tx and Rx queues. Add functions to create and destroy these
queues, which will be further used while performing ndo_bpf
operations to set up XSK Tx/Rx queues for a given port.

In the destroy Rx queue sequence add teardown wait to ensure
that all the descriptors including the TDCM (teardown completion
marker) have been serviced and freed to avoid any sort of descriptor
leaks.
