d0320f7500 drivers:net: Remove dma_alloc_coherent OOM messages
I believe these error messages are already logged
on allocation failure by warn_alloc_failed and so
get a dump_stack on OOM.

Remove the unnecessary additional error logging.

Around these deletions:

o Alignment neatening.
o Remove unnecessary casts of dma_alloc_coherent.
o Hoist assigns from ifs.

18d359ceb0 pch_gbe, ptp_pch: Fix the dependency direction between these drivers
In commit a24006ed12 ('ptp: Enable clock
drivers along with associated net/PHY drivers') I wrongly made
PTP_1588_CLOCK_PCH depend on PCH_GBE.  The dependency is really the
other way around.  Therefore make PCH_GBE select PTP_1588_CLOCK_PCH
and remove the 'default y' from the latter.

a24006ed12 ptp: Enable clock drivers along with associated net/PHY drivers
Where a PTP clock driver is associated with a net or PHY driver, it
should be enabled automatically whenever that driver is enabled.
Therefore:

- Make PTP clock drivers select rather than depending on PTP_1588_CLOCK
- Remove separate boolean options for PTP clock drivers that are built
  as part of net driver modules.  (This also fixes cases where the PTP
  subsystem is wrongly forced to be built-in.)
- Set 'default y' for PTP clock drivers that depend on specific net
  drivers but are built separately

42a7ccef0a ptp: Make PTP_1588_CLOCK select rather than depend on PPS
PTP hardware clock drivers that select PTP_1588_CLOCK must currently
also select PPS.  For those drivers that don't, the user must enable
PPS, then enable PTP_1588_CLOCK, then the driver.  Simplify things for
developers and users by putting this selection in one place.

a35279f002 pch_gbe: don't reset MAC_RX on FIFO overflow
Currently, when FIFO_ERR happens, we stop the dma, wait for it to become
idle and then reset the whole MAC_RX logic (and after that we must re-set
multicast addresses and also re-enable MAC_RX when we're finally ready to
accept new packets). This leads to CRC errors on high number of incoming
packets and is not needed according to the datasheet.

This patch fixes it by the following steps:

1) remove this reset in pch_gbe_stop_receive(), which causes some functions
to not be used anywhere
2) remove already unused functions pch_gbe_wait_clr_bit_irq() and
pch_gbe_mac_reset_rx() to correctly build
3) move pch_gbe_enable_mac_rx() out of pch_gbe_start_receive() to
pch_gbe_up() where it's only needed after we've removed the MAC_RX reset
4) rename pch_gbe_start/stop_receive() to pch_gbe_enable/disable_dma_rx()
to more precisely reflect what the functions are now doing.

After these changes we already don't see the CRC errors and gain some
increase in RX processing speed.

If we were in RX_FIFO_ERR state and entered pch_gbe_napi_poll(), we'll
anyway clean some rx space and thus can continue to receive more packets.
Currently, we re-set the RX_FIFO_ERR in situations when we've exhausted our
budget for RX cleaning or cleaned some TX packets. Removing it gives us
+20%-40% speed increase and a lot less of RX_FIFO_ERRors reported.

0f79657984 pch_gbe: Fix build error by selecting all the possible dependencies.
Fengguang reported a kernel build failure as following:
drivers/built-in.o: In function `pch_gbe_ioctl':
pch_gbe_main.c:(.text+0x510370): undefined reference to `pch_ch_control_write'
pch_gbe_main.c:(.text+0x510393): undefined reference to `pch_ch_control_write'
pch_gbe_main.c:(.text+0x5103b3): undefined reference to `pch_ch_control_write'
...

It's a regression by commit da1586461. The root cause is that
the CONFIG_PPS is not set there, consequently CONFIG_PTP_1588_CLOCK
can not be set anyway, which finally causes ptp_pch and pch_gbe_main
build failures.

As David prefers to use *select* to fix such module co-dependency issues,
this patch explicitly selects all the possible dependencies of PCH_PTP.

da1586461e pch_gbe: Fix PTP dependencies.
The config combination:

        CONFIG_PCH_GBE=y
        CONFIG_PCH_PTP=y
        CONFIG_PTP_1588_CLOCK=m

doesn't work, because then you have a built-in kernel
object (the PCH_PTP code) referring to symbols in a
module (PTP_1588_CLOCK).

Fix this like IXGBE, by using "select PTP_1588_CLOCK"
instead of a "depends on".

d344c4f310 pch_gbe: reprogram multicast address register on reset
The reset logic after a Rx FIFO overrun will clear the programmed
multicast addresses. This patch fixes the issue by reprogramming the
registers after the reset.

The commit eefc48b ("pch_gbe: reprogram multicast address register on
reset") tried to fix this problem, but it introduces unnecessary
codes. In fact, all multicast addresses have been saved in netdev->mc,
So we can call pch_gbe_set_multi() directly after reset_hw and
reset_rx.

This commit kills 50+ line codes

2b53d07891 pch_gbe: Do not abort probe on bad MAC
If the MAC is invalid or not implemented, do not abort the probe. Issue
a warning and prevent bringing the interface up until a MAC is set manually
(via ifconfig $IFACE hw ether $MAC).

Tested on two platforms, one with a valid MAC, the other without a MAC. The real
MAC is used if present, the interface fails to come up until the MAC is set on
the other. They successfully get an IP over DHCP and pass a simple ping and
login over ssh test.

This is meant to allow the Inforce SYS940X development board:
http://www.inforcecomputing.com/SYS940X_ECX.html
(and others suffering from a missing MAC) to work with the mainline kernel.
Without this patch, the probe will fail and the interface will not be created,
preventing the user from configuring the MAC manually.

This does not make any attempt to address a missing or invalid MAC for the
pch_phub driver.

9d9779e723 drivers/net: Add module.h to drivers who were implicitly using it
The device.h header was including module.h, making it present for
most of these drivers.  But we want to clean that up.  Call out the
include of module.h in the modular network drivers.

8b0c11679f net: Remove unnecessary driver assignments of ethtool_ringparam fields to zero
Per comments from Ben Hutchings on a previous patch, sweep the floors
a little removing unnecessary assignments of zero to fields of struct
ethtool_ringparam in driver code supporting ethtool -g.

aaba215ca0 MII: fix Kconfig dependencies for MII
MII Kconfig option is apart of the core networking drivers and
by default NET_CORE is enabled so drivers selecting MII will
have MII enabled as well.  It was found using the randconfig
option during testing, MII would be selected but NET_CORE
could be disabled.  This caused a dependency error.

Resolved the dependency by selecting NET_CORE when MII is
selected.

88f07484cc drivers/net/ethernet/*: Enabled vendor Kconfig options
Based on finds for Stephen Rothwell, where current defconfig's
enable a ethernet driver and it is not compiled due to the newly
added NET_VENDOR_* component of Kconfig.

This patch enables all the "new" Kconfig options so that current
defconfig's will continue to compile the expected drivers.  In
addition, by enabling all the new Kconfig options does not add
any un-expected options.
