netns: introduce the net_hash_mix "salt" for hashes
There are many possible ways to add this "salt", thus I made this
patch to be the last in the series to change it if required.
Currently I propose to use the struct net pointer itself as this
salt, but since this pointer is most often cache-line aligned, shift
this right to eliminate the bits, that are most often zeroed.
After this, simply add this mix to prepared hashfn-s.
For CONFIG_NET_NS=n case this salt is 0 and no changes in hashfn
appear.

net: Fix test for VLAN TX checksum offload capability
Selected device feature bits can be propagated to VLAN devices, so we
can make use of TX checksum offload and TSO on VLAN-tagged packets.
However, if the physical device does not do VLAN tag insertion or
generic checksum offload then the test for TX checksum offload in
dev_queue_xmit() will see a protocol of htons(ETH_P_8021Q) and yield
false.
This splits the checksum offload test into two functions:
- can_checksum_protocol() tests a given protocol against a feature bitmask
- dev_can_checksum() first tests the skb protocol against the device
features; if that fails and the protocol is htons(ETH_P_8021Q) then
it tests the encapsulated protocol against the effective device
features for VLANs
