====================
slight optimization of addr compare for net modules
This is the second patchset for slight optimization of address compare,
mainly for net tree, just following the Joe's opinion, it will help review
the code for maintainers and supports.
v2: Change some style for patch 2.
According Eric's suggestion, use the ether_addr_equal_64bits to instead
of ether_addr_equal for patch 19.
In fact, there are a lot of places which could use ether_addr_equal_64bits
to instead of ether_addr_equal, but not this time, thanks for Joe's
opinion.
v3: Change some style for patch 11/19:
(net: packetengines: slight optimization of addr compare).
Joe pointed out that is_broadcast_ether_addr(addr) would be appropriate here,
but this should be left alone and not in this patch, so fix it later.
In the patch (net: caif: slight optimization of addr compare), the operand for
memcmp is not mac address, so it is unsuitable to use the ether_addr_equal
to compare a non mac address, so remove the patch from the series.

netlink: specify netlink packet direction for nlmon
In order to facilitate development for netlink protocol dissector,
fill the unused field skb->pkt_type of the cloned skb with a hint
of the address space of the new owner (receiver) socket in the
notion of "to kernel" resp. "to user".
At the time we invoke __netlink_deliver_tap_skb(), we already have
set the new skb owner via netlink_skb_set_owner_r(), so we can use
that for netlink_is_kernel() probing.
In normal PF_PACKET network traffic, this field denotes if the
packet is destined for us (PACKET_HOST), if it's broadcast
(PACKET_BROADCAST), etc.
As we only have 3 bit reserved, we can use the value (= 6) of
PACKET_FASTROUTE as it's _not used_ anywhere in the whole kernel
and not supported anywhere, and packets of such type were never
exposed to user space, so there are no overlapping users of such
kind. Thus, as wished, that seems the only way to make both
PACKET_* values non-overlapping and therefore device agnostic.
By using those two flags for netlink skbs on nlmon devices, they
can be made available and picked up via sll_pkttype (previously
unused in netlink context) in struct sockaddr_ll. We now have
these two directions:
- PACKET_USER (= 6) -> to user space
- PACKET_KERNEL (= 7) -> to kernel space
Partial `ip a` example strace for sa_family=AF_NETLINK with
detected nl msg direction:
syscall: direction:
sendto(3, ...) = 40 /* to kernel */
recvmsg(3, ...) = 3404 /* to user */
recvmsg(3, ...) = 1120 /* to user */
recvmsg(3, ...) = 20 /* to user */
sendto(3, ...) = 40 /* to kernel */
recvmsg(3, ...) = 168 /* to user */

bnx2x: no error when RSS configuration fails
It's possible for VMs with older versions of bnx2x to run over a hypervisor
with latest driver. If a VF in such a VM does not support RSS configuration,
the PF driver in the hypervisor will print an error message to system logs.
This changes the error message into a debug message, as this is very likely
a false alarm for an older VF (i.e., VF manages to work properly; PF simply
cannot configure the additional queues for it).

bnx2x: add Big-Endian ethtool comment
There's a known issue that using `ethtool -e' flips the endianity of the
written data, i.e., using `ethtool -E' to dump eeprom image and than using
`ethtool -e' to re-write that same image will result in an image where
the data has the opposite endianity.
Sadly, this cannot be fixed as there are already various tools deployed
based on the endianity of the eeprom read/write.
Instead, a comment is added to the code to help explain why this is un-fixable.

bnx2x: Add support for Multi-Function UNDI
This adds the ability for bnx2x to load after UNDI is used in the
preboot environment on a multi-function interface which is not the first
interface of a given device.
Notice a side-effect is that the order by which the functions are probed and
thus interfaces appear might change, as this patch utilizes the EPROBE_DEFER
return value (and mechanism).

Merge branch 'addr_compare'
Ding Tianhong says:
====================
slight optimization of addr compare for some modules
Joe Perches add ether_addr_equal_unaligned to test if
possibly unaligned to u16 Ethernet addresses are equal.
If CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, this uses
the slightly faster generic routine ether_addr_equal,
otherwise this uses memcmp.
So I use the recently added and possibly more efficient
ether_addr_equal_unaligned to instead of memcmp for slight
optimization.
v2: Because a lot of places are already using 16b aligned MAC
address for both operands, so use the ether_addr_equal to
instead of ether_addr_equal_unaligned.Thanks for Joe, Alex
and Antonio's opinions.
Also remove the patch for bridge.
v3: According Joe's suggestion, the patch
(net: slight optimization of addr compare for some modules)
should be broken into several patches, and it will be good
to review for maintainers. So I will send rest of the patches
for first step, and next step, I will seperate the netdev patch
and send them by another patchset for net-next.
also fix some changelog.
v3.5 Change some style for patch 8 and patch 13. Thanks for
Sergei's suggestion.
