Side effect: it allows user to force-disable some offloads on the bond

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.

- 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It's dubious that the loss of outdated packets will matter much for a)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.

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

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.
