Clean up array_rd32 so that it uses igb_rd32 the same as rd32, per the
suggestion of Alexander Duyck, and use io_addr in more places, so that
we don't have the need to call E1000_REMOVED (which simply looks for a
null hw_addr) nearly as much.

The i210 has two EEPROM access registers that are located in
non-standard offsets: EEARBC and EEMNGCTL. EEARBC was fixed previously
and EEMNGCTL should also be corrected.

In addition to interrupt driven target time output events, the i210
also has two programmable clock outputs. These clocks support periods
between 16 nanoseconds and 140 milliseconds. This patch implements
the periodic output function using the clock outputs when possible,
falling back to the target time for longer periods.

On some devices, the internal PLL circuit occasionally provides the
wrong clock frequency after power up. The probability of failure is less
than one failure per 1000 power cycles. When the failure occurs, the
internal clock frequency is around 1/20 of the correct frequency.

For i350 VLAN stripping for VMs is not enabled in the VMOLR register but in
the DVMOLR register. Making the changes accordingly. It's not necessary to
unset the E1000_VMOLR_STRVLAN bit on i350 as the hardware will simply ignore
it.
Without this change if a VLAN is configured for a VF assigned to a guest
via (i.e.)
ip link set p1p1 vf 0 vlan 10
the VLAN tag will not be stripped from packets going into the VM. Which they
should be because the VM itself is not aware of the VLAN at all.

In rare circumstances, it's possible a descriptor writeback will occur
before a timestamped Tx packet will go out on the wire, leading to the
driver believing the hardware failed to timestamp the packet. Schedule a
work item for 82576 and use the available time sync interrupt registers
on 82580 and above to account for this.
