The original way of changing ring length was to completely
tear down the lif's queue structure and then rebuild it, while
running the risk of allocations that might fail in the middle
and leave us with a broken driver.
Instead, we can set up all the new queue and descriptor
allocations first, then swap them out and delete the old
allocations. If the new allocations fail, we report the error,
stay with the old setup and continue running. This gives us
a safer path, and a smaller window of time where we're not
processing traffic.

This patch fixes a bunch of issues in cpsw_ndo_vlan_rx_kill_vid()
- pm_runtime_get_sync() returns non zero value. This results in
non zero value return to caller which will be interpreted as error.
So overwrite ret with zero.
- If VID matches with port VLAN VID, then set error code.
- Currently when VLAN interface is deleted, all of the VLAN mc addresses
are removed from ALE table, however the return values from ale function
calls are not checked. These functions can return error code -ENOENT.
But that shouldn't happen in a normal case. So add error print to
catch the situations so that these can be investigated and addressed.
return zero in these cases as these are not real error case, but only
serve to catch ALE table update related issues and help address the
same in the driver.

Following commit e186967865 ("mwifiex: Prevent memory corruption
handling keys") the mwifiex driver fails to authenticate with certain
networks, specifically networks with 256 bit keys, and repeatedly asks
for the password. The kernel log repeats the following lines (id and
bssid redacted):
mwifiex_pcie 0000:01:00.0: info: trying to associate to '<id>' bssid <bssid>
mwifiex_pcie 0000:01:00.0: info: associated to bssid <bssid> successfully
mwifiex_pcie 0000:01:00.0: crypto keys added
mwifiex_pcie 0000:01:00.0: info: successfully disconnected from <bssid>: reason code 3
Tracking down this problem lead to the overflow check introduced by the
aforementioned commit into mwifiex_ret_802_11_key_material_v2(). This
check fails on networks with 256 bit keys due to the current storage
size for AES keys in struct mwifiex_aes_param being only 128 bit.
To fix this issue, increase the storage size for AES keys to 256 bit.
