When one tries to add eth as a port into team and that eth is already in
use by other rx_handler device (macvlan, bond, bridge, ...) a bug in
team_port_add() causes that IFF_TEAM_PORT flag is set before rx_handler
is registered. In between, netdev nofifier is called and
team_device_event() sees IFF_TEAM_PORT and thinks that rx_handler_data
pointer is set to team_port. But it isn't.
Fix this by reordering rx_handler register and IFF_TEAM_PORT priv flag
set so it is very similar to how bonding does this.

bnx2x: `fixes' patch-series
This series contains mostly bug fixes, but never the less is intended
for `net-next' and not `net', as:
- Some of the fixes are quite insignificant [`VF clean statistics',
`ethtool -d might cause timeout in log'].
- Some only recently were submitted to `net-next' [`Fix timesync endianity'].
- Some are not usually compiled as part of the kernel [`Fix stop-on-error'].
Dave - please consider applying this series to `net-next'; If you prefer,
I can break this series into 2 parts [one for `net' and the other for
`net-next'] - but personally I don't see much benefit in it.

This introduces 2 new relaxations in the bnx2x driver regarding GRO:
1. Don't prevent SW GRO if HW GRO is disabled.
2. If all aggregations are disabled, when GRO configuration changes
there's no need to perform an inner-reload [since it will have no
actual effect].

This changes slightly the set of registers read during `ethtool -d'.
Without this change, it's possible the HW will generate a grc Attention which
will be logged into system logs as `grc timeout'.

As reported by Jesper Dangaard Brouer, for high packet rates the
overhead of having another indirect call in the TX path is
non-trivial.
There is the indirect call itself, and then there is all of the
reloading of the state to refetch the tail pointer value and
then write the device register.
Move to a more passive scheme, which requires very light modifications
to the device drivers.
The signal is a new skb->xmit_more value, if it is non-zero it means
that more SKBs are pending to be transmitted on the same queue as the
current SKB. And therefore, the driver may elide the tail pointer
update.
Right now skb->xmit_more is always zero.

Make is_kdump_kernel() accessible from modules
I'm re-spinning this patchset. At the begining it was suggested to use a
different name for the parameter, but at the end [3] the resolution was to
leave it as it is in this patch.
Drivers need to know if running from kdump kernel in order to change their
memory profile - since kdump environment is limited by available memory.
Currently there are drivers that are using reset_devices as suggested in [2].
In [2] it was suggested to use reset_devices, but the context was, to enable
driver to know when the hardware device is needed to be reset, and not if this
is a kdump environment. We think that is_kdump_kernel() is better suited to
select between different memory profiles.
The first patch in this patchset exports a needed symbol in order to make
is_kdump_kernel() accessible from the drivers. The rest of the patches change
from reset_devices to is_kdump_kernel() in 2 networking drivers.
The idea of this patchset was suggested by Vivek Goyal.
Tested (only build) and applied on top of commit 8fc54f6: ("net: use
reciprocal_scale() helper")

In order to make is_kdump_kernel() accessible from modules, need to
make elfcorehdr_addr exported.
This was rejected in the past [1] because reset_devices was prefered in
that context (reseting the device in kdump kernel), but now there are
some network drivers that need to reduce memory usage when loaded from
a kdump kernel. And in that context, is_kdump_kernel() suits better.
