[PATCH v2 0/4] tg3: add support for Ethernet core in BCM4785

[PATCH v2 0/4] tg3: add support for Ethernet core in BCM4785

[Hauke Mehrtens]

These patches are adding support for the Ethernet core found in the 
BCM4705/BCM4785 SoC.

This is based on current master of davem/net-next.git.

v2:
 * use of struct sprom in ssb_gige_get_macaddr() instead of accessing 
   the nvram directly
 * add return value to ssb_gige_get_macaddr()
 * try to read the mac address from ssb core before accessing the own 
   registers.
 * fix two checkpatch warnings

Hauke Mehrtens (4):
  ssb: get mac address from sprom struct for gige driver
  ssb: add missing method ssb_gige_get_macaddr
  tg3: make it possible to provide phy_id in ioctl
  tg3: add support for Ethernet core in bcm4785

[PATCH v2 1/4] ssb: get mac address from sprom struct for gige driver

[Hauke Mehrtens]

The mac address is already stored in the sprom structure by the
platform code of the SoC this Ethernet core is found on, it just has to
be fetched from this structure instead of accessing the nvram here.
This patch also adds a return value to indicate if a mac address could
be fetched from the sprom structure.

This patch could cause merge problems with the mips tree. This version, 
removing the usage of nvram_getenv and nvram_parse_macaddr, should be 
used.

[PATCH v2 3/4] tg3: make it possible to provide phy_id in ioctl

[Hauke Mehrtens]

In OpenWrt we currently use a switch driver which uses the ioctls to
configure the switch in the phy. We have to provide the phy_id to do
so, but without this patch this is not possible.

[PATCH v2 4/4] tg3: add support for Ethernet core in bcm4785

[Hauke Mehrtens]

The BCM4785 or sometimes named BMC4705 is a Broadcom SoC which a
Gigabit 5750 Ethernet core. The core is connected via PCI with the rest
of the SoC, but it uses some extension.

This core does not use a firmware or an eeprom.

Some devices only have a switch which supports 100MBit/s, this
currently does not work with this driver.

This patch was original written by Michael Buesch <m@bues.ch> and is in
OpenWrt for some years now.

This was tested on a Linksys WRT610N V1 and older versions of this patch
were tested by other people on different devices.
