9e39f7c5b3 s2io: Generate complete messages using single line DBG_PRINTs
Single line log messages should be emitted by a single call
where possible.

Converted multiple calls to DBG_PRINT to single call form.
Removed "s2io:" preface from DBG_PRINTs.

The DBG_PRINT macro now emits a log level and is surrounded by
a do {...} while (0)

All s2io log output is now prefaced with KBUILD_MODNAME ": "
via pr_fmt.

The DBG_PRINT macro should probably be converted to use the
dev_<level> form eventually.

ffb5df6ce7 s2io.c: Standardize statistics accessors
Regularize the declaration and uses of
	struct config_param *config = &sp->config;
	struct mac_info *mac_control = &sp->mac_control;
and use
	struct stat_block *stats = mac_control->stats_info;
	struct swStat *swstats = &stats->sw_stat;
	struct xpakStat *xstats = &stats->xpak_stat;
and convert the longish uses like
	nic->mac_control.stats_info->sw_stat.<foo>
to
	swstats-><foo>
etc.

This also makes the statistics code marginally smaller
and presumably faster.

2394905f67 ucc_geth: Implement suspend/resume and Wake-On-LAN support
This patch implements suspend/resume and WOL support for UCC Ethernet
driver.

We support two wake up events: wake on PHY/link changes and wake
on magic packet.

In some CPUs (like MPC8569) QE shuts down during sleep, so magic packet
detection is unusable, and also on resume we should fully reinitialize
UCC structures.

2db9517ef3 TI DaVinci EMAC: delay DaVinci EMAC initialization
On TI's DA850/OMAP-L138 EVM, MAC address is stored in SPI
flash which is accessed using MTD interface.

This patch delays the initialization of DaVinci EMAC driver
by changing module_init to late_initcall. This helps SPI and
MTD drivers to get initialized before EMAC thereby enabling
EMAC driver to read the MAC address while booting and use it.

Tested with NFS on DM644x, DM6467, DA830/OMAP-L137 and
DA850/OMAP-L138 EVMs.

b2014ff8ac qlge: Get rid of 'default' rx_ring type.
Currently we have three types of RX rings.

1) Default ring - services rx_ring for broadcast/multicast, handles

2) TX completion ring - handles only outbound completions.

3) RSS ring - handles only inbound completions.

This patch gets rid of the default ring type and moves it's functionality
into the first RSS ring.  This makes better use of MSIX vectors since
they are a limited resource on some platforms.
