Macvlan currently inherits all of its features from the lower
device. When lower device disables offload support, this causes
macvlan to disable offload support as well. This causes
performance regression when using macvlan/macvtap in bridge
mode.
It can be easily demonstrated by creating 2 namespaces using
macvlan in bridge mode and running netperf between them:
MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 10.0.0.1 () port 0 AF_INET

Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
87380 16384 16384 20.00 1204.61
To restore the performance, we add software offload features
to the list of "always_on" features for macvlan. This way
when a namespace or a guest using macvtap initially sends a
packet, this packet will not be segmented at macvlan level.
It will only be segmented when macvlan sends the packet
to the lower device.

====================
Please pull this batch of fixes intended for the 3.14 stream...
For the mac80211 bits, Johannes says:
"This time I have a fix to get out of an 'infinite error state' in case
regulatory domain updates failed and two fixes for VHT associations: one
to not disconnect immediately when the AP uses more bandwidth than the
new regdomain would allow after a change due to association country
information getting used, and one for an issue in the code where
mac80211 doesn't correctly ignore a reserved field and then uses an HT
instead of VHT association."
For the iwlwifi bits, Emmanuel says:
"Johannes fixes a long standing bug in the AMPDU status reporting.
Max fixes the listen time which was way too long and causes trouble
to several APs."
Along with those, Bing Zhao marks the mwifiex_usb driver as _not_
supporting USB autosuspend after a number of problems with that have
been reported.

this is a pull request of 8 patches. Oliver Hartkopp contributes a patch which
removes the CAN FD compatibility for CAN 2.0 sockets, as it turns out that this
compatibility has some conceptual cornercases. The remaining 7 patches are by
me, they address a problem in the flexcan driver. When shutting down the

This patch fixes a CPDMA RX Descriptor leak that occurs after taking
the interface down when the CPSW is in Dual MAC mode. Previously
the CPSW_ALE port was left open up which causes packets to be received
and processed by the RX interrupt handler and were passed to the
non active network interface where they were ignored.
The fix is for the slave_stop function of the selected interface
to disable the respective CPSW_ALE Port from forwarding packets. This
blocks traffic from being received on the inactive interface.
