* Due to HW bug, LAN8700 sometimes does not detect presence of energy in the
Ethernet cable in Energy Detect Power-Down mode (e.g while EDPWRDOWN bit is
set, the ENERGYON bit does not asserted sometimes). This is a common bug of
LAN87xx family of PHY chips.

Without this, the presence of a netxen device in a bond will not trigger
LRO support to be enabled at the bond level, even while it is enabled on
the slave itself.
This change becomes necessary when NETIF_F_LRO is added to
netdev_features.h's NETIF_F_ONE_FOR_ALL.

Currently, all bonding devices come up, and claim to have LRO support,
which ethtool will let you toggle on and off, even if none of the
underlying hardware devices actually support it. While the bonding driver
takes precautions for slaves that don't support all features, this is at
least a little

At present, you can create a bond, containing only underlying slaves that do
not support LRO, and the bond will happily claim to support LRO, and allow
LRO to be toggled on and off by ethtool. While things actually do function
fine in the scenario, and this is merely cosmetic, its a bit misleading
Commit 10e4ea751 ("net: Fix race condition in store_rps_map") has moved the
manipulation of the rps_needed jump label under a spinlock. Since changing
the state of a jump label may sleep this is incorrect and causes warnings
during runtime.
Make rps_map_lock a mutex to allow sleeping under it.

For some reason, the s2io driver has never filled in vlan_features. If
that's fully intentional, then this patch should be dropped. If its not,
then this patch is necessary to maintain some functionality of slave s2io
devices in a bonding group.
Without this, the presence of a s2io device in a bon

This private net_device flag can be set by drivers to inform that a
device runs fine without a qdisc attached. This was formerly done by
setting tx_queue_len to zero.
