WCN3990 firmware sends rx duration for each peer as part of

mv88e6xxx: Avoid false positive Lockdep splats
When acquiring the GPIO interrupt line for the switch, it is possible
to trigger lockdep splats. These are false positives, the mutex is in
a different IRQ descriptor. But fix it anyway, since it could mask
real locking issues.

net: dsa: mv88e6xxx: Release lock while requesting IRQ
There is no need to hold the register lock while requesting the GPIO
interrupt. By not holding it we can also avoid a false positive
lockdep splat.

lock(&desc->request_mutex);

&desc->request_mutex refer to two different mutex. #1 is the GPIO for
the chip interrupt. #2 is the chained interrupt between global 1 and
global 2.
Add lockdep classes to the GPIO interrupt to avoid this.

tls: Return type of non-data records retrieved using MSG_PEEK in recvmsg
The patch enables returning 'type' in msghdr for records that are
retrieved with MSG_PEEK in recvmsg. Further it prevents records peeked
from socket from getting clubbed with any other record of different
type when records are subsequently dequeued from strparser.
For each record, we now retain its type in sk_buff's control buffer
cb[]. Inside control buffer, record's full length and offset are already
stored by strparser in 'struct strp_msg'. We store record type after
'struct strp_msg' inside 'struct tls_msg'. For tls1.2, the type is
stored just after record dequeue. For tls1.3, the type is stored after
record has been decrypted.
Inside process_rx_list(), before processing a non-data record, we check
that we must be able to return back the record type to the user
application. If not, the decrypted records in tls context's rx_list is
left there without consuming any data.
