This extra BCM54612E code in PHY driver isn't really aneg specific. Even
without it aneg works OK but the problem is no packets pass through PHY.

Moreover putting this code inside config_aneg callback didn't allow
resuming PHY correctly. When driver called phy_stop and phy_start it was
putting PHY machine into RESUMING state. After that machine was
switching into AN and NOLINK without ever calling phy_start_aneg. This
prevented this extra setup from being called and PHY didn't work.

This change has been verified to fix network on BCM47186B0 SoC device
with BCM54612E.

Dmitry reported warnings occurring in __skb_gso_segment() [1]

All SKB_GSO_DODGY producers can allow user space to feed
packets that trigger the current check.

We could prevent them from doing so, rejecting packets, but
this might add regressions to existing programs.

It turns out our SKB_GSO_DODGY handlers properly set up checksum
information that is needed anyway when packets needs to be segmented.

By checking again skb_needs_check() after skb_mac_gso_segment(),
we should remove these pesky warnings, at a very minor cost.

In the current version, the matchall internal state is split into two
structs: cls_matchall_head and cls_matchall_filter. This makes little
sense, as matchall instance supports only one filter, and there is no
situation where one exists and the other does not. In addition, that led
to some races when filter was deleted while packet was processed.

Unify that two structs into one, thus simplifying the process of matchall
creation and deletion. As a result, the new, delete and get callbacks have
a dummy implementation where all the work is done in destroy and change
callbacks, as was done in cls_cgroup.

In particular, this is used when creating a macvlan child interface for
VRRP in a VRF configuration, allowing the interface creator to specify
directly what master interface should be inherited by the child,
without having to deal with asynchronous complications and potential

Recent commit 34393529 ("be2net: fix MAC addr setting on privileged
BE3 VFs") allows privileged BE3 VFs to set its MAC address during
initialization. Although the initial MAC for such VFs is already
programmed by parent PF the subsequent setting performed by VF is OK,
but in certain cases (after fresh boot) this command in VF can fail.

The MAC should be initialized only when:
1) no MAC is programmed (always except BE3 VFs during first init)
2) programmed MAC is different from requested (e.g. MAC is set when
   interface is down). In this case the initial MAC programmed by PF
   needs to be deleted.

The adapter->dev_mac contains MAC address currently programmed in HW so
it should be zeroed when the MAC is deleted from HW and should not be
filled when MAC is set when interface is down in be_mac_addr_set() as
no programming is performed in this case.

Example of failure without the fix (immediately after fresh boot):

# ip link set eth0 up  <- eth0 is BE3 PF
be2net 0000:01:00.0 eth0: Link is Up

# echo 1 > /sys/class/net/eth0/device/sriov_numvfs  <- Create 1 VF
...
be2net 0000:01:04.0: Emulex OneConnect(be3): VF  port 0

# ip link set eth8 up  <- eth8 is created privileged VF
be2net 0000:01:04.0: opcode 59-1 failed:status 1-76
RTNETLINK answers: Input/output error

# echo 0 > /sys/class/net/eth0/device/sriov_numvfs  <- Delete VF

# echo 1 > /sys/class/net/eth0/device/sriov_numvfs  <- Create it again

So far were were allocating struct bgmac in 3 places: platform code,
bcma code and shared bgmac_enet_probe function. The reason for this was
bgmac_enet_probe:
1) Requiring early-filled struct bgmac
2) Calling alloc_etherdev on its own in order to use netdev_priv later

This solution got few drawbacks:
1) Was duplicating allocating code
2) Required copying early-filled struct
3) Resulted in platform/bcma code having access only to unused struct

Solve this situation by simply extracting some probe code into the new
bgmac_alloc function.

Commit 7318166c ("net: dsa: bcm_sf2: Add support for
ethtool::rxnfc") added a new object to build: bcm_sf2_cfp.o, but in
doing so, we essentially just built this object and no longer bcm_sf2.o.

Fix this by creating a module named bcm-sf2.ko which links in bcm_sf2.o
and bcm_sf2_cfp.o.

~1160 mlx5 counters ~= order 4 allocation which is unlikely to succeed
under memory pressure. Convert them to vzalloc() as ethtool_get_regs() does.
Also take care of drivers without counters similar to
commit 67ae7cf1 ("ethtool: Allow zero-length register dumps again")
and reduce warn_on to warn_on_once.
