-Wunused-but-set-variable generates a compile warning for lcs' tasklet
function. Invoked functions contain already error handling; thus
additional return code checking is not needed here.

Remove unused return code handling. The claw driver is mostly dead, so
just make sure it keeps compiling without warnings.

Set rx csum default to hw checksumming again.
Remove sysfs interface for rx csum (checksumming) and TSO (large_send).
With the new hw_features it does not work to keep the old sysfs
interface in parallel. Convert options.checksum_type to new hw_features.

Driver checks if the previous dump has been cleared before taking the dump.

Sending mbox cmds require multiple steps of writing to the DB register and polling
for an ack. Gettting interrupted in the middle by a signal breaks the mbox protocol.

This should also fix updating of vlan_features and propagating changes to
VLAN devices on the bond.
Side effect: it allows user to force-disable some offloads on the bond
interface.
Note: NETIF_F_VLAN_CHALLENGED is managed by bond_fix_features() now.

capability is added for the devices which support internal MAC loopback mode.
So when enabled, it enables internal-MAC loopback.

Resending this patch with few changes.
Avoid multiple queues when MSI or MSI-X not available
Limit number of Tx queues to 1 if MSI/MSI-X support is not configured in
the kernel. This will make number of tx and rx queues equal when MSI/X
is not configured thus providing better performance.

Start/stop TX queue is controlled by TX queue "used" counter.
It is incremented while WRBs are posted to TX queue and
decremented when TX completions are received. This counter was
getting decremented before HW is informed about processing of TX
completions. As used counter is decremented, transmit function
posts new WRBs and creates completion queue full scenario in HW.

Currently EHEA reports to ethtool as supporting 10M, 100M, 1G and

However, when connected to FIBRE the only supported speed is 10G
full-duplex, and the other speeds and modes are only supported
when connected to twisted pair.

The USB protocol this driver implements appears to require 2 bytes of
padding in front of each received packet. This used to be equal to
the value of NET_IP_ALIGN on x86, so the driver abused that constant
and mostly worked, but this is no longer the case. The driver also
mixed up the URB and packet lengths, resulting in 2 bytes of junk at
the end of the skb.
Introduce a private constant for the 2 bytes of padding; fix this
confusion and check for the under-length case.

Using the vmxnet3 driver produces a lockdep warning because
vmxnet3_set_mc(), which is called with mc->mca_lock held, takes
adapter->cmd_lock. However, there are a couple of places where
adapter->cmd_lock is taken with softirqs enabled, lockdep warns that a
softirq that tries to take mc->mca_lock could happen while
adapter->cmd_lock is held, leading to an AB-BA deadlock.
I'm not sure if this is a real potential deadlock or not, but the
simplest and best fix seems to be simply to make sure we take cmd_lock
with spin_lock_irqsave() everywhere -- the places with plain spin_lock
just look like oversights.
The full enormous lockdep warning is:

Unknown 8168 chips did not have any PLL power method set as they
did not inherit a default family soon enough. Fix it.

- 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.

There is no real firmware version yet but the manpage of ethtool
is rather terse about the driver information.
Former output:

$ ethtool -i eth0

Current output:

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.

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.

Pull read_lock(&bond->lock) and BOND_IS_OK() to bond_start_xmit() from
mode-dependent xmit functions.
netif_running() is always true in hard_start_xmit.

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
top of a lower dev at once.
