Previously we swapped the tx_packets, tx_bytes and tx_dropped counters
with rx_packets, rx_bytes and rx_dropped counters, respectively. This
behaviour is correct and expected for VF representors but it should not
be swapped for physical port mac representors.

There is no real need for the users of timecounters to define cyclecounter
and timecounter variables separately. Since timecounter will always be
based on cyclecounter, have cyclecounter struct as member of timecounter

This allows sending GSO maximum values when configuring a device.
The values are advisory. Most devices will ignore them but for some
pseudo devices such as veth pairs they can be set.
Example:
# ip link add dev vm1 type veth peer name vm2 gso_max_size 32768

Allow GSO maximum segments and size as netlink parameters on input.

Veth's can be used in environments (like Azure) where the underlying
network device is impacted by large GSO packets. This patch allows
gso maximum values to be passed in when creating the device via
netlink.
In theory, other pseudo devices could also use netlink attributes
to set GSO maximums but
This is another way of addressing the GSO maximum performance issues for
containers on Azure. What happens is that the underlying infrastructure uses
a overlay network such that GSO packets over 64K - vlan header end up cause
either guest or host to have do expensive software copy and fragmentation

READ_ONCE() now implies smp_read_barrier_depends(), which means that
the instances in arpt_do_table(), ipt_do_table(), and ip6t_do_table()
are now redundant. This commit removes them and adjusts the comments.
