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.

This function is also called to detect and clear roce errors
while enabling the rdma error interrupts. However there is no hns
reset requested for this case. This can cause issue of wrong
reset_type used with subsequent hns reset as the

mlxsw: spectrum_acl: Don't take rtnl mutex for region rehash

Jiri says:

During region rehash, a new region is created with a more optimized set
of masks (ERPs). When transitioning to the new region, all the rules
from the old region are copied one-by-one to the new region. This
transition can be time consuming and currently done under RTNL lock.

In order to remove RTNL lock dependency during region rehash, introduce
multiple smaller locks guarding dedicated structures or parts of them.
That is the vast majority of this patchset. Only patch #1 is simple
cleanup and patches 12-15 are improving or introducing new selftests.

For MR ACL profile is does not make sense to do periodical rehashes, as
there is only one mask in use during the whole vregion lifetime.
Therefore periodical work is scheduled but the rehash never happens.
So allow to enable/disable rehash for the whole group, which is added
per-profile. Disable rehashing for MR profile.

Addition to the vregion list is done only in case the rehash is enable
on the particular vregion. Also, the addition is moved after delayed
work init to avoid schedule of uninitialized work
from vregion_rehash_intrvl_set(). Symmetrically, deletion from
the list is done before canceling the delayed work so it is
not scheduled by vregion_rehash_intrvl_set() again.

net: dsa: microchip: add MIB counters support

This series of patches is to modify the KSZ9477 DSA driver to read MIB
counters periodically to avoid overflow.

The MIB counters should be read only when there is link.  Otherwise it is
a waste of time as hardware never increases the counters.

Functions are added to check the port link status so that MIB counters
read call is used efficiently.

v4
- Use readx_poll_timeout
- Fix using mutex in a timer callback function problem
- use dp->slave directly instead of checking whether it is valid
- Add port_cleanup function in a separate patch
- Add a mutex so that changing device variables is safe

v3
- Use netif_carrier_ok instead of checking the phy device pointer

v2
- Create macro similar to readx_poll_timeout to use with switch
- Create ksz_port_cleanup function so that variables like on_ports and
  live_ports can be updated inside it

v1
- Use readx_poll_timeout
- Do not clear MIB counters when port is enabled
- Do not advertise 1000 half-duplex mode when port is enabled
- Do not use freeze function as MIB counters may miss counts
====================
