Although most of the NIC drivers are epoch ready, due to peer pressure
switch over to opt-in instead of opt-out for epoch.

Instead of IFF_NEEDSEPOCH, provide IFF_KNOWSEPOCH. If driver marks
itself with IFF_KNOWSEPOCH, then ether_input() would not enter epoch
when processing its packets.

Now this will create recursive entrance in epoch in >90% network
drivers, but will guarantee safeness of the transition.

Mark several tested drivers as IFF_KNOWSEPOCH.

Remove a singleton in the DPAA driver, to allow multiple fman instances

Some devices (P5040, P4080) have multiple frame managers in their DPAA
subsystems. This was prevented by use of a softc singleton in the DPAA
driver. Since if_dtsec(4) has moved to be a child of fman, it can access
the fman device data via the parent object.

Make DPAA work in 64-bit mode

Rework the dTSEC and FMan drivers to be more like a full bus relationship,
so that dtsec can use bus_alloc_resource() instead of trying to handle the
offset from the dts. This required taking some code from the sparc64 ebus
driver to allow subdividing the fman region for the dTSEC devices.

This adds some support for ARM as well as 64-bit. 64-bit on PowerPC is
currently not working, and ARM support has not been completed or tested on the
FreeBSD side.

As this was imported from a Linux tree, it includes some Linux-isms

future.

Make dpaa work with only slightly modified Linux device trees.

Linux has a slightly different device tree definition for DPAA than originally
done in the FreeBSD driver. This changes the driver to be mostly compatible
with the Linux device tree definitions. Currently the differences are:

bman-portals: compatible = "fsl,bman-portals" (Linux is "simple-bus")
qman-portals: compatible = "fsl,qman-portals" (Linux is "simple-bus")
fman: compatible = "fsl,fman" (Linux is "simple-bus")

The Linux device tree doesn't specify anything for rgmii in the mdio. This
change still requires the device tree to specify the phy-handle, and doesn't yet
support tbi.
