In monitor mode, if channel is initially configured from 5G
band and then moved to channel from 2G band, packets are still
received on MAC-0 RXDMA2SW ring since IMPS is disabled for both
MACs. Since driver reaps only MAC-1 RXDMA2SW ring, ring full
condition is hit for the MAC-0 ring causing ring backpressure.
Fix is to drop packets received on the non-monitoring MAC
ring.

Rx desc pool have a flag to identify whether frag or nbuf
operation needs to be performed for alloc, map, prep and
free buffer for monitor dest buffer.
This flag will be set only for mon destination desc pool,
if RX_MON_MEM_FRAG feature is enabled.
In all other case, It will be set to Zero and default nbuf
operation will be taken.
This flag get initialized at the time of pdev rx_desc_pool
initialization and gets reset while pdev deinit.
Mon destination buffer will have support for frag if
