When the kdump kernel started, the HNS3 driver fail to register:
[14.753340] hns3 0000:7d:00.0: Alloc umv space failed, want 512, get 0
[14.795034] hns3 0000:7d:00.0: add uc mac address fail, ret =-22.
By default, the HNS3 driver will use about 512M memory, but
usually the reserved memory of kdump kernel is 576M, so the HNS3
driver fail to register. This patch reduces the memory use in
kdump kernel to about 16M.
And when the kdump kernel starts, we must clear ucast mac address
first to avoid add fail.

The original patch didn't consider the case that autoneg process
finishes successfully but both link partners have no mode in common.
In this case there's no link, nevertheless we may be interested in
what the link partner advertised.
Like phydev->link we set phydev->autoneg_complete in
genphy_update_link() and use the stored value in genphy_read_status().
This way we don't have to read register BMSR again.

There are two reasons for this.
First, the xmit_more flag conceptually doesn't fit into the skb, as
xmit_more is not a property related to the skb.
Its only a hint to the driver that the stack is about to transmit another
packet immediately.
Second, it was only done this way to not have to pass another argument
to ndo_start_xmit().
We can place xmit_more in the softnet data, next to the device recursion.
The recursion counter is already written to on each transmit. The "more"
indicator is placed right next to it.
Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more
to check the "more packets coming" hint.
skb->xmit_more is retained (but always 0) to not cause build breakage.
This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/
conversions. Remaining drivers are converted in the next patches.

The AQR107 family has SGMII statistics counters. Let's expose them to
ethtool. To interpret the counters correctly one has to be aware that
rx on SGMII side is tx on ethernet side. The counters are populated
by the chip in 100Mbps/1Gbps mode only.
v2:
- add constant AQR107_SGMII_STAT_SZ
- add struct aqr107_priv to be prepared for more private data fields
- let aqr107_get_stat() return U64_MAX in case of an error

This patch improves few aspects of genphy_read_status():
- Don't initialize lpagb, it's not needed.
- Move initializing phydev->speed et al before the if clause.
- In auto-neg case, skip populating lp_advertising if we
don't have a link. This avoids quite some unnecessary
MDIO reads in case of phylib polling mode.

With the introduction of flow_action_for_each pedit actions are no
longer grouped together, instead pedit actions are broken out per
32 byte word. This results in an inefficient use of the action list
that is pushed to hardware where each 32 byte word becomes its own
action. Therefore we combine groups of 32 byte word before sending
the action list to hardware.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kvzalloc(size, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kvzalloc(struct_size(instance, entry, count), GFP_KERNEL);
Notice that, in this case, variable size is not necessary, hence
it is removed.
This code was detected with the help of Coccinelle.

The use of zero-sized array causes undefined behaviour when it is not
the last member in a structure. As it happens to be in this case.
Also, the current code makes use of a language extension to the C90
standard, but the preferred mechanism to declare variable-length
types such as this one is a flexible array member, introduced in
C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last. Which is beneficial
to cultivate a high-quality code.
