During interrupt mask initialization, bitmap of tx ring
mask and reo dest ring mask are filled in host mode based
on the number of rings.
When NSS offload mode and dynamic HW mode are enabled,
interrupt reset is done based on modified ring count.
This is causing invalid hal_srng access for interrupt
context which are not reset.
So, resetting tx ring mask and reo ring mask based on host
mode ring count. Also reset when mask value is non-zero.

Currently the rx tids are getting setup for the
self peer in monitor mode. This leads to sending
commands to the reorder-hw and the hardware generates
its responses.
In Monitor mode, none of these rings are reaped, since
the reorder-hw is not used. This opens up a possibility
of backpressure on the reorder-hw rings.
Skip setting up the rx tids for monitor mode
self peer, since they are not used.

currently qdf_nbuf_len is being used to get the length of
the tx pkt, but this API also interprets the nbuf CB field
to adjust the length if extra_frags are present.
The concept of extra_frags is applicable only for legacy
drivers but in lithium as cb is not reset in the driver the
qdf_nbuf_len API is mis-calculating the length if extra_frag
field in cb is set by any network stack protocol.
To avoid this qdf_nbuf_headlen API is used to get the length
of the TX pkt.

Currently, we decrement active_work_cnt in a while loop in delayed
register worker and later on make a "allow_l1" call to enable L1ss.
The bus suspend routine depends on the value of active_work_cnt to
determine if any register writes are pending. In case there are, bus
suspend is rejected.
As a result its possible that when bus suspend happens, the
delayed worker while processing the last remaining enqueued
write, makes the active_work_cnt to 0. This will allow the bus suspend
routine to continue to disable the bus, even before the
delayed-reg-worker has called allow_l1 and run to completion. This may
lead to a NOC error while calling "allow_l1" API from
delayed-reg-worker.
Hence, move the decrement of active_work_cnt to the very end in
hal_reg_write_work function.
