net/rxrpc: Use an IS_ERR test rather than a NULL test
In case of error, the function rxrpc_get_transport returns an ERR
pointer, but never returns a NULL pointer. So after a call to this

A simplified version of the semantic patch that makes this change is
as follows:

estimators to find the one belonging to a stats object. There's no need to use
an rwlock, as we only have one reader. Also reorder the members of the
estimator structure slightly to avoid padding overhead. This can't be done
with the stats object as the members are currently copied to our user space

bonding: Don't destroy bonding master when removing slave via sysfs
It is wrong to destroy a bonding master from a context that uses the sysfs
of that bond. When last IPoIB slave is unenslaved from by writing to a
sysfs file (for bond0 this would be /sys/class/net/bond0/bonding/slaves)
the driver tries to destroy the bond. This is wrong and can lead to a
lockup or a crash. This fix lets the bonding master stay and relies on
the user to destroy the bonding master if necessary (i.e. before module
ib_ipoib is unloaded)

igb: remove igb_init_managability as it is deprecated
igb_init_managability does not actually perform any function as the two
registers it attempts to write are both read only on the host. This patch
removes the function and all references to it from the driver.

atl1: deal with hardware rx checksum bug
The L1 hardware contains a bug that flags a fragmented IP packet
as having an incorrect TCP/UDP checksum, even though the packet
is perfectly valid and its checksum is correct. There's no way to
distinguish between one of these good packets and a packet that
actually contains a TCP/UDP checksum error, so all we can do is
allow the packet to be handed up to the higher layers and let it
be sorted out there.
Add a comment describing this condition and remove the code that
currently fails to handle what may or may not be a checksum error.
