net: ti: icssg-prueth: Fix packet handling for XDP_TX
While transmitting XDP frames for XDP_TX, page_pool is used to get the DMA buffers (already mapped to the pages) and need to be freed/reycled once the transmission is complete. This need not be explicitly done by the driver as this is handled more gracefully by the xdp driver while returning the xdp frame. __xdp_return() frees the XDP memory based on its memory type, under which page_pool memory is also handled. This change fixes the transmit queue timeout while running XDP_TX. logs: [ 309.069682] icssg-prueth icssg1-eth eth2: NETDEV WATCHDOG: CPU: 0: transmit queue 0 timed out 45860 ms [ 313.933780] icssg-prueth icssg1-eth eth2: NETDEV WATCHDOG: CPU: 0: transmit queue 0 timed out 50724 ms [ 319.053656] icssg-prueth icssg1-eth eth2: NETDEV WATCHDOG: CPU: 0: transmit queue 0 timed out 55844 ms ...
