The CPDMA_TX_PRIORITY_MAP in real is vlan pcp field priority mapping
register and basically replaces vlan pcp field for tagged packets.
So, set it to be 1:1 mapping. Otherwise, it will cause unexpected

There is no need for two loop variables, both i an
The connection timers of an llc sock could be still flying
after we delete them in llc_sk_free(), and even possibly
after we free the sock. We could just wait synchronously
here in case of troubles.
Note, I leave other call paths as they are, since they may
not have to wait, at least we can change

I want to ask if it is time to start using poorman function overloading
with _b_c_e(). There are millions of allocation functions for example,
all slightly difference, and people will add more. Seeing /proc interfaces

From: Ben Greear
This is similar to ETHTOOL_GSTATS, but it allows you to specify
flags. These flags can be used by the driver to decrease the
amount of stats refreshed. In particular, this helps with ath10k
since getting the firmware stats can be slow.

This enables users to request fewer stats to be refreshed
in cases where firmware does not need to be probed.

This keeps us from crashing in certain test cases where we
bring up many (1000, for instance) mac-vlans with IPv6
enabled in the kernel. This bug has been around for a
very long time.
Until a real fix is found (and for stable), maybe it
is better to return an incomplete fib wal
