In a configuration with CONFIG_BRIDGE set to 'm' and CONFIG_ROCKER
set to 'y', undefined references occur at link time:

> drivers/built-in.o: In function `rocker_port_fdb_learn_work':
> /home/jim/linux/drivers/net/ethernet/rocker/rocker.c:3014: undefined
> reference to `br_fdb_external_learn_del'
> /home/jim/linux/drivers/net/ethernet/rocker/rocker.c:3016: undefined
> reference to `br_fdb_external_learn_add'

This patch fixes these by declaring CONFIG_ROCKER as being dependent
on CONFIG_BRIDGE.

Our FW can support several fastpath HSI [for backward compatibility] but up
until now VFs were always configured to use latest fastpath HSI [although VF
driver might be older and use an older fastpath HSI].

For linux drivers, the differences are insignificant since driver never
utilized features that were overridden by the HSI change. But for VMs running
other operating systems this might be a problem.
In addition, eventually FW might change fastpath HSI in such a manner that
backward compatibility WILL break unless configured with proper version.

This patch fixes the issue for other operating system VMs, as well as lays
the ground work for forward compatibility in regard to the fastpath HSI.

The comment says that the built-in strncmp didn't work. That is not
surprising, as apparently "str" semantics are not really what is
wanted (hint: de4x5_strncmp only stops when two different bytes are
encountered or the end is reached; not if either byte happens to be
0). de4x5_strncmp is actually a memcmp (except for the signature and
that bytes are not necessarily treated as unsigned char); since only
the boolean value of the result is used we can just replace
de4x5_strncmp with memcmp.

Redefine REALTEK_USB_DEVICE for the desired USB interface for probe().
There are three USB interfaces for the device. USB_CLASS_COMM and

that GPHY major revision is in bits 15:12, minor in bits 11:8 and patch
level is in bits 7:4.

Introduce a small heuristic which checks for the old scheme first, tests
for the new scheme and finally attempts to catch reserved values and

This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.

It modifies drivers implementation of set/get_rxfh accordingly.

This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.

User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.

Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

Also this cleans up two other spots where skb_pad was called but the length

the padding length added via __skb_put.
