BCMA is a Broadcom specific bus with devices AKA cores. All recent BCMA
based SoCs have gigabit ethernet provided by the GBit MAC core. This
patch adds driver for such a cores registering itself as a netdev. It
has been tested on a BCM4706 and BCM4718 chipsets.

In the kernel tree there is already b44 driver which has some common
things with bgmac, however there are many differences that has led to
the decision or writing a new driver:
1) GBit MAC cores appear on BCMA bus (not SSB as in case of b44)
2) There is 64bit DMA engine which differs from 32bit one
3) There is no CAM (Content Addressable Memory) in GBit MAC
4) We have 4 TX queues on GBit MAC devices (instead of 1)
5) Many registers have different addresses/values
6) RX header flags are also different

The driver in it's state is functional how, however there is of course
place for improvements:
1) Supporting more net_device_ops
2) SUpporting more ethtool_ops
3) Unaligned addressing in DMA
4) Writing separated PHY driver

We have skb_mac_header_was_set() helper to tell if mac_header
was set on a skb. We would like the same for transport_header.

__netif_receive_skb() doesn't reset the transport header if already
set by GRO layer.

Note that network stacks usually reset the transport header anyway,
after pulling the network header, so this change only allows
a followup patch to have more precise qdisc pkt_len computation

Paul Gortmaker says:

====================
I'd like to propose that we get rid of these old 8390 EISA drivers.
Of the five deleted here, I wrote four -- and while that doesn't give
me any authority for deletion above anyone else, it does at least
allow me to comment on the absolute absence of anyone reaching
out to the driver author for assistance in the last dozen years.

Eventually we'll probably get rid of EISA bus support, since in
x86, the hardware is close to 20 years old and already too resource
constrained to be useful today.  However there might still be
a few DEC Alpha enthusiasts with old EISA machines kept alive,
and so I expect we'll have to wait a bit longer to get unanimous
agreement to proceed with the full EISA removal (although I'd
love to be proven wrong on that).

Most of the DEC Alpha machines shipped in a PCI configuration, and
even the few that were EISA had DEC tulip based ethernet and no
reason to be needing the inferior 8390 technology.  So the interest
here for any possible DEC enthusiasts with EISA boxes about these
old 8390 drivers should be nil.

These really were rare cards -- in fact the smc-ultra32 is the only
one that I'd ever seen in person.  Even back in the mid 90's when
the drivers were written, I would guess that the user base was less
than 10 people across all of them.

The following patch was created with --irreversible-delete for
ease of review (it skips showing the content of files that are
deleted); however the complete patch can be pulled as per below.

way to make sure we don't access about to be freed or already

The NS8390 chip was essentially the 1st widespread PC ethernet
chip, starting its life on 8 bit ISA cards in the late 1980s.
Even with better technologies available (bus mastering etc)
the 8390 managed to get used on a few rare EISA cards in the
early to mid 1990s.

The EISA bus in the x86 world was largely confined to systems
ranging from 486 to 586 (essentially 200MHz or lower, and less
than 100MB RAM) -- i.e. machines unlikely to be still in service,
and even less likely to be running a 3.9+ kernel.

On top of that, only one of the five really ever was considered
non-experimental; the smc-ultra32 was the one -- since it was
largely just an EISA version of the popular smc-ultra ISA card.
All the others had such a tiny user base that they simply never
could be considered anything more than experimental.
