axgbe: Various stability improvements

Hook in RSS glue.

Default to "off" for the split header feature to ensure netmap
compatibility.

Change the PCS indirection register values based on hardware type
(ported from Linux).

Move tunable settings to sysctl_init() and set the defaults there.
Ensure it's called at the right time by moving it back.

Reset PHY RX data path when mailbox command times out (Ported from
Linux).

Check if VLAN HW tagging is enabled before assuming a VLAN tag
is present in a descriptor.

Disable the hardware filter since multicast traffic is dropped
in promisc mode.

Remove unnecessary return statement.

Missing sfp_get_mux, causing a race between ports to read
SFP(+) sideband signals.

Validate and fix incorrectly initialized polarity/configuration
registers.

Remove unnecessary SFP reset.

axgbe_isc_rxd_pkt_get has no error state, remove unnecessary
big packet check.

Enable RSF to prevent zero-length packets while in Netmap mode.

DMA cache coherency update (ported from Linux).

axgbe: fix some link related issues

By default, axgbe driver does a receiver reset after predefined number
of retries for the link to come up. However, this receiver reset
doesn't always suffice, due to an hardware issue.
In that case, as a workaround, a complete phy reset is necessary.
This patch introduces a sysctl that can be set to 1 to let the driver
reset the phy completely, rather than just doing receiver reset.
The workaround will be removed once the issue is fixed by means
of firmware update.

This patch also fixes the handling of the direct attach cables
properly.

axgbe: driver changes for netmap support

AMD 10GbE hardware is designed to have two buffers per receive descriptor to
support split header feature. For this purpose, the driver was designed to use
2 iflib freelists per receive queue. So, that buffers from 2 freelists are used
to refill an entry in the receive descriptor. The current design holds good
with regular data traffic.

But, when netmap comes into play, the current design will not fit in. The
current netmap interfaces and netmap implementation in iflib doesn't seem
to accomodate the design of 2 freelists per receive queue. So, exercising
Netmap capability with inbuilt tools like bridge, pkt-gen doesn't work with
the 2 freelists driver design.

So, the driver design is changed to accomodate the current netmap interfaces
and netmap implementation in iflib by using single freelist per receive queue
approach when Netmap capability is exercised without disturbing the current
2 freelists approach.
The dev.ax.sph_enable tunable can be set to 0 to configure the single
free list mode.

Thanks to Stephan Dewt for his Initial set of code changes for the stated
problem.

This patch has the driver for 10Gigabit Ethernet controller in AMD
SoC. This driver is written compatible to the Iflib framework. The
existing driver is for the old version of hardware. The submitted
driver here is for the recent versions of the hardware where the Ethernet
controller is PCI-E based.
