Rafał Miłecki 217a55a338 bgmac: return error on failed PHY write
Some callers may want to know if PHY write succeed. Also make PHY
functions static, they are not exported anywhere.

Rafał Miłecki e9ba103931 bgmac: fix "cmdcfg" calls for promisc and loopback modes
The last (bool) parameter in bgmac_cmdcfg_maskset says if the write
should be made, even if value didn't change. Currently driver doesn't
match the specs about (not) forcing some changes. This makes it follow
them.

Hauke Mehrtens 7e6c63f03d tg3: add support for Ethernet core in bcm4785
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.

Ariel Elior 4c133c39ae bnx2x: SR-IOV version compatibility bugfix
When posting a message on the bulletin board, the PF calculates crc
over the message and places the result in the message. When the VF
samples the Bulletin Board it copies the message aside and validates
this crc. The length of the message is crucial here and must be the
same in both parties. Since the PF is running in the Hypervisor and
the VF is running in a Vm, they can possibly be of different versions.
As the Bulletin Board is designed to grow forward in future versions,
in the VF the length must not be the size of the message structure
but instead it should be a field in the message itself.

Michael Chan ad9b4359c7 cnic, bnx2x: Add CNIC_DRV_STATE_HANDLES_IRQ to ethdev->drv_state
In INTA mode, cnic and bnx2x share the same IRQ.  During chip reset,
for example, cnic will stop servicing IRQs after it has shutdown the
cnic hardware resources.  However, the shared IRQ is still active as
bnx2x needs to finish the reset.  There is a window when bnx2x does
not know that cnic is no longer handling IRQ and things don't always
work properly.

Add a flag to tell bnx2x that cnic is handling IRQ.  The flag is set
before the first cnic IRQ is expected and cleared when no more cnic
IRQs are expected, so there should be no race conditions.

Yuval Mintz 9969085e7e bnx2x: Added FW GRO bridging support
Since submit 621b4d6 the bnx2x driver support FW GRO.
However, when using the device with GRO enabled in bridging
scenarios throughput is very low, as the bridge expects all
incoming packets to be passed with CHECKSUM_PARTIAL -
a demand which is satisfied by the SW GRO implementation,
but was missed in the bnx2x driver implementation (which returned
CHECKSUM_UNNECESSARY).

Now, given that the traffic is supported by FW GRO (TCP/IP),
the bnx2x driver calculates the pseudo checksum by itself,
passing skbs with CHECKSUM_PARTIAL and giving a much better
throughput when receiving GRO traffic.

The flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.

Rafał Miłecki dd4544f054 bgmac: driver for GBit MAC core on BCMA bus
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

Jiri Pirko aaeb6cdfa5 remove init of dev->perm_addr in drivers
perm_addr is initialized correctly in register_netdevice() so to init it in
drivers is no longer needed.

Ariel Elior 6411280ac9 bnx2x: Segregate SR-IOV code
In this patch the SR-IOV code is segregated from the main bulk of
the bnx2x code. The CONFIG_BNX2X_SRIOV define is added to Broadcom's
Kconfig, and allows the elision of the building of all the SR-IOV
support code in the driver.
The define is dependant on the kernel CONFIG_PCI_IOV configuration
define.

Jiri Pirko 7826d43f2d ethtool: fix drvinfo strings set in drivers
Use strlcpy where possible to ensure the string is \0 terminated.
Use always sizeof(string) instead of 32, ETHTOOL_BUSINFO_LEN
and custom defines.
Use snprintf instead of sprint.
Remove unnecessary inits of ->fw_version
Remove unnecessary inits of drvinfo struct.

Nithin Nayak Sujir b681b65d4f tg3: Remove IS_ENABLED(CONFIG_HWMON) check
Commit de0a41484c added Kconfig logic to
select HWMON and removed all the IS_ENABLED(CONFIG_HWMON) checks in the
tg3.c file. It missed this one check in the header.

Update version to 3.129 and update copyright year.

Michael Chan 857001f06f tg3: Improve PCI function number detection.
Simplify the code to detect PCI function number on 5717, 5719, and 5720.
If shared memory does not have proper signature, read the function number
from register directly.
