As linux-5.0 is coming up soon, the howto.rst document can be

IVDF - individual virtual device filtering. Allows to set per vlan

The cpsw supports unicast filtering as for real as for vlan devices
now, but has no flag set for that. As result, once macvlan or vlan
adds new ucast address the cpsw is silently toggled to promiscuous
mode. That's smth not expected, so patch fixes it.
A unicast address for vlan has to be presente
The cpsw can filter multicast addresses only per vlan. Thus if mcast

added for every created vlan consuming ALE table w/o reason. In order to

One of the reasons of this proposition is safety and performance -

Update vlan mc and uc addresses with VID tag while propagating

It allows at end driver level to distinguish addresses belonging

The vlan device address is held separately from uc/mc lists and
handled differently. The vlan dev address is bound with real device
address only if it's inherited from init, in all other cases it's
separate address entry in uc list. With vid set, the address becomes
not inherited from real device a

Yeah, I guess x86 _should_ really do __this_cpu_xchg() as just a
read-write pair.
In general, a read-write pair is probably always the right thing to
do, and the onl

Implementation of tc_poll_timeout() is almost a 100% copy-and-paste of
the code for regmap_read_poll_timeout(). Replace copied code with a
call to the original. No functional change intended.

Everyone:
This series contains various improvements (at least in my mind) that I
made to tc358767 while working with the code of the driver. Hopefuly
each patch is self explanatory.
Feedback is welcome!
Thanks,

Tc_wait_pll_lock() is always called as a follow-up for updating
PLLUPDATE and PLLEN bit of a given PLL control register. To simplify
things, merge the two operation into a single helper function
tc_pllupdate_pllen() and convert the rest of the code to use it. No
functional change intended.
