mac_pton() parses MAC address in form XX:XX:XX:XX:XX:XX and only in that form.

mac_pton() doesn't dirty result until it's sure string representation is valid.

mac_pton() doesn't care about characters _after_ last octet,
it's up to caller to deal with it.

mac_pton() diverges from 0/-E return value convention.
Target usage:

	if (!mac_pton(str, whatever->mac))
		return -EINVAL;
	/* ->mac being u8 [ETH_ALEN] is filled at this point. */
	/* optionally check str[3 * ETH_ALEN - 1] for termination */

Use mac_pton() in pktgen and netconsole for start.

- RTL_GIGA_MAC_NONE is a fake index so put it at the end of the
  enumeration and shift everybody.
- RTL_GIGA_MAC_VER_17 / RTL_GIGA_MAC_VER_16 ordering fixed. Though
  not wrong it was confusing enough to wonder if things were right.

Renaming rtl_chip_info was not strictly necessary. It allows to
check the patch for the correct use of the indexes though.

Invocation of rtl8169_rx_interrupt from rtl8169_reset_task was originally
intended to retrieve as much packets as possible from the rx ring when a
reset was needed. Nowadays rtl8169_reset_task is only scheduled, with
some delay
a. from the tx timeout watchdog
b. when resuming
c. from rtl8169_rx_interrupt itself

It's dubious that the loss of outdated packets will matter much for a)
and b). c) does not need to call itself again.

The implementation was a bit krusty.

The 10s rtl8169_phy_timer timer has been (was ?) required with older
8169 for adequate phy operation when full gigabit is advertised in
autonegotiated mode. The timer does nothing if the link is up.
Otherwise it keeps resetting the phy until things improve.

- the device private data field phy_1000_ctrl_reg was used to
  schedule the timer. Avoid it and save a few bytes.

- rtl8169_set_settings
  pending timer is disabled before changing the link settings as
  rtl8169_phy_timer is not always needed (see the removed test in
  rtl8169_phy_timer).

- rtl8169_set_speed
  the requested link parameters may not match the chipset : bail out
  early on failure.

- rtl8169_open
  Calling rtl8169_request_timer is redundant with
  -> rtl8169_open
     -> rtl8169_init_phy
        -> rtl8169_set_speed
           -> mod_timer
  The latter always enables the phy timer whereas the former did not
  for RTL_GIGA_MAC_VER_01. It should not make things worse but only
  time will tell if reality agrees.

- rtl8169_request_timer : unused yet. Removed.

- rtl8169_delete_timer : useless. Bloat. Removed.

Side effect : the timer may kick in if the TBI is enabled. I do not
know if the TBI has ever been used in real life.

Shorten chipset version test.

No functional change.

Careful readers will notice that the 'supports_gmii' flag is deduced
from the device PCI id. Though less specific than the chipset related
RTL_GIGA_MAC_VER_XY, it is good enough to detect a GMII deprieved 810x.
Some features push for a device specific configuration (improved jumbo
frame support for instance). 'supports_gmii' will follow this path
if / when the device PCI id test stops working.

veth devices dont use the batched device unregisters yet.

Since veth are a pair of devices, it makes sense to use a batch of two
unregisters, this roughly divides dismantle time by two.

Fix this by changing dellink() callers to always provide a non NULL
head. (Idea from Michał Mirosław)

This patch also handles macvlan case : We now dismantle all macvlans on

This patch enables ethtool to set the loopback mode on a given interface.
By configuring the interface in loopback mode in conjunction with a policy
route / rule, a userland application can stress the egress / ingress path
exposing the flows of the change in progress and potentially help developer(s)
understand the impact of those changes without even sending a packet out
on the network.

Following set of commands illustrates one such example -
    a) ip -4 addr add 192.168.1.1/24 dev eth1
    b) ip -4 rule add from all iif eth1 lookup 250
    c) ip -4 route add local 0/0 dev lo proto kernel scope host table 250
    d) arp -Ds 192.168.1.100 eth1
    e) arp -Ds 192.168.1.200 eth1
    f) sysctl -w net.ipv4.ip_nonlocal_bind=1
    g) sysctl -w net.ipv4.conf.all.accept_local=1
    # Assuming that the machine has 8 cores
    h) taskset 000f netserver -L 192.168.1.200
    i) taskset 00f0 netperf -t TCP_CRR -L 192.168.1.100 -H 192.168.1.200 -l 30

This patch makes use of the EVENT_DEV_OPEN flag introduced recently to
fix one out of memory issue, which can be reproduced on omap3/4 based
pandaboard/beagle XM easily with steps below:

	- enable runtime pm
	echo auto > /sys/devices/platform/usbhs-omap.0/ehci-omap.0/usb1/1-1/1-1.1/power/control

	- ifconfig eth0 up

	- then out of memroy happened, see [1] for kernel message.

Follows my analysis:
	- 'ifconfig eth0 up' brings eth0 out of suspend, and usbnet_resume
	is called to schedule dev->bh, then rx urbs are submited to prepare for
	recieving data;

	- some usbnet devices will produce garbage rx packets flood if
	info->reset is not called in usbnet_open.

	- so there is no enough chances for usbnet_bh to handle and release
	recieved skb buffers since many rx interrupts consumes cpu, so out of memory
	for atomic allocation in rx_submit happened.

This patch fixes the issue by simply not allowing schedule of usbnet_bh until device
is opened.

PCIe connections should be expressed as GT/s (GigaTransfers per second)
instead of the current Gb/s (Gigabits per second).  In addition, it is
incorrect because (due to PCIe gen 1 & 2 having a 20% overhead) the
actually data rate, when expressed in Gb/s, is only 80% of the rate of
GT/s.

Introduce buffered read/writes which greatly improves performance on
parts with large EEPROMs.

Previously reading/writing a word requires taking/releasing of synchronization
semaphores which adds 10ms to each operation. The optimization is to
read/write in buffers, but make sure the semaphore is not held for >500ms
according to the datasheet.

Since we can't read the EEPROM page size ixgbe_detect_eeprom_page_size() is
used to discover the EEPROM size when needed and keeps the result in
word_page_size for the rest of the run time.

Use buffered reads for ethtool -e.

Recent commits have changed how EEPROM size is checked and if the size
word is misconfigured, the driver will fail to load.  This patch adds a
check for invalid size word in the EEPROM and uses default size instead
for 82576 parts.
