The white list commands might not be implemented if the controller does
not actually support the white list. So check the supported commands
first before issuing these commands. Not supporting the white list is
the same as supporting a white list with zero size.

A bug report (https://bugzilla.kernel.org/show_bug.cgi?id=107071) noted
that the follwoing ip command is failing with v4.3:
$ ip route add 10.248.5.0/24 dev bond0.250 table vlan_250 src 10.248.5.154
RTNETLINK answers: Invalid argument
021dd3b8a1 changed the lookup of the given preferred source address to
use the table id passed in, but this assumes the local entries are in the
given table which is not necessarily true for non-VRF use cases. When
validating the preferred source fallback to the local table on failure.
Fixes: 021dd3b8a1 ("net: Add routes to the table associated with the device")

Sasha reported the following lockdep warning:
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(sk_lock-AF_INET);
lock(rtnl_mutex);
lock(sk_lock-AF_INET);
lock(rtnl_mutex);
This is due to that for IP_MSFILTER and MCAST_MSFILTER, we take
rtnl lock before the socket lock in setsockopt() path, but take
the socket lock before rtnl lock in getsockopt() path. All the
rest optnames are setsockopt()-only.
Fix this by aligning the getsockopt() path with the setsockopt()
path, so that all mcast socket path would be locked in the same
order.
Note, IPv6 part is different where rtnl lock is not held.
Fixes: 54ff9ef36b ("ipv4, ipv6: kill ip_mc_{join, leave}_group and ipv6_sock_mc_{join, drop}")

While the ring allocation is done by a single function, sh_eth_ring_init(),
the ring deallocation was split into two functions (almost always called
one after the other) for no good reason. Merge sh_eth_free_dma_buffer()
into sh_eth_ring_free() which allows us to save space not only on the
direct calls of the former function but also on the sh_eth_ring_init()'s
simplified error path...

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Fix crash when TEE target is used with no --oif, from Eric Dumazet.
2) Oneliner to fix a crash on the redirect traffic to localhost
infrastructure when interface has not yet an address, from
Munehisa Kamata.
3) Oneliner not to request module all the time from nfnetlink due to
wrong type value, from Florian Westphal.
I'll make sure these patches 1 and 2 hit -stable.
====================
The conflict in net/netfilter/xt_TEE.c was minor, a change
to the 'oif' selection overlapping a function signature
change for the nf_dup_ipv{4,6}() routines.
