It turns out that there's some other malarky going on behind the scenes

In theory the barriers are required to cope with write combining and

1. Before the first write to guarantee that previous writes to the region
have been done
2. Before the last write to guarantee that write to the last dword/qword is
done after previous writes
Barriers are inserted before in the assumption that it is better to
postpone barriers as much as it is possible (more chances that the
operation has already been already done and barrier does not stall CPU).
On x86 and amd64 bus space write barriers are just compiler memory barriers
which are definitely required.

the CPU nexus.
* Add ahb as a possible bus attachment
* Lay a comment down to remind me or whoever else ends up trying
to debug why the EEPROM isn't mapped in as to what's going on.
I noticed that openwrt/linux does this, citing "instability", so
until they figure out why I'm going to disable it here as well.
Tested:
* QCA AP135 - QCA955x SoC + AR8327 switch.
So, it turns out that the AR8327 has 7 ports internally:
* GMAC0 / external (CPU) MAC0
* GMAC1 / port1 -> GMAC5 / port5: external switch port PHYs
* GMAC6 / external (CPU) MAC1
Now, depending upon how things are wired up, the second CPU port (MAC1)
can be wired to either the switch (port6), or through port5's PHY, bypassing
the GMAC+switch entirely. Ie, it can pretend to be a boring PHY, saving
system designers from having to include a separate PHY for a "WAN" port.
Here's the rub - the AP135 board (QCA955x SoC) hooks up arge0 to
the second CPU port on the AR8327, but it's hooked up as RGMII.
So, in order to hook it up to the rest of the switch, it isn't configured
as a separate PHY - OpenWRT has it setup as connected via RGMII to
GMAC6 and (I'm guessing) it's set to be a WAN port by configuring up
port-based VLANs or something.
Thus, with a port mask of 0x3f, GMAC6 was never allowed to receive traffic
from any other port. It could transmit fine, but not receive anything.
So, now it works enough for me to continue doing board bootstrapping.
Note, this isn't enough to make the QCA955x + AR8327 work - there's
a bunch of uncommitted work to both the platform SoC (interrupt handling,
ethernet, etc) and the ethernet switch (register access space, setup, etc)
that needs to happen. However, this particular change is also relevant to
other SoCs, like the AR934x and AR7161, both of which can be glued to
this switch.

It is disabled by default but users can set IFCAP_TXCSUM on the
netmap ifnet (ifconfig ncxl0 txcsum) to override netmap and force
the hardware to calculate and insert proper IP and L4 checksums in
outbound frames.

Preliminary tests indicate 32 Mpps on tx, 24 Mpps on rx
with source and receiver on two different ports of the same 40G card.
Optimizations are likely possible.
The code follows closely the one for ixgbe so i do not
expect stability issues.

To delay packets from a particular TX queue by a particular time, write a value
into the TX Pace table s.t. pace time <= TX Pace Clock Period * (2 ^ pace value)
- the TX pace clock is 1/13 of the system clock, so its period should be 104 or
52 ns depending on whether turbo mode is active.
EFX_TX_PACE_CLOCK_BASE added by me.

E.g. on interface bring up or multicast addresses addition.

It is one more place missed in the previous fix.
Most likely is was just memory leak on the error handling path since
typically efsys_mem_t is filled in by zeros on allocation.
