bonding: correctly verify for the first slave in bond_enslave
After commit
1f718f0f4f97145f4072d2d72dcf85069ca7226d ("bonding: populate
neighbour's private on enslave"), we've moved the actual 'linking' in the
end of the function - so that, once linked, the slave is ready to be used,
and is not still in the process of enslaving.
However, 802.3ad verified if it's the first slave by looking at the
if (bond_first_slave(bond) == new_slave)
which, because we've moved the linking to the end, became broken - on the
first slave bond_first_slave(bond) returns NULL.
Fix this by verifying if the prev_slave, that equals bond_last_slave(), is
actually populated - if it is - then it's not the first slave, and vice
versa.

net: add adj_list to save only neighbours
Currently, we distinguish neighbours (first-level linked devices) from
non-neighbours by the neighbour bool in the netdev_adjacent. This could be
quite time-consuming in case we would like to traverse *only* through
neighbours - cause we'd have to traverse through all devices and check for
this flag, and in a (quite common) scenario where we have lots of vlans on
top of bridge, which is on top of a bond - the bonding would have to go
through all those vlans to get its upper neighbour linked devices.
This situation is really unpleasant, cause there are already a lot of cases
when a device with slaves needs to go through them in hot path.
To fix this, introduce a new upper/lower device lists structure -
adj_list, which contains only the neighbours. It works always in
pair with the all_adj_list structure (renamed from upper/lower_dev_list),
i.e. both of them contain the same links, only that all_adj_list contains
also non-neighbour device links. It's really a small change visible,
currently, only for __netdev_adjacent_dev_insert/remove(), and doesn't
change the main linked logic at all.
Also, add some comments a fix a name collision in
netdev_for_each_upper_dev_rcu() and rework the naming by the following
rules:
netdev_(all_)(upper|lower)_*
If "all_" is present, then we work with the whole list of upper/lower
devices, otherwise - only with direct neighbours. Uninline functions - to
get better stack traces.

net: neighbour: use source address of last enqueued packet for solicitation
Currently we always use the first member of the arp_queue to determine
the sender ip address of the arp packet (or in case of IPv6 - source
address of the ndisc packet). This skb is fixed as long as the queue is
not drained by a complete purge because of a timeout or by a successful
response.
If the first packet enqueued on the arp_queue is from a local application
with a manually set source address and the to be discovered system
does some kind of uRPF checks on the source address in the arp packet
the resolving process hangs until a timeout and restarts. This hurts
communication with the participating network node.
This could be mitigated a bit if we use the latest enqueued skb's
source address for the resolving process, which is not as static as
the arp_queue's head. This change of the source address could result in
better recovery of a failed solicitation.

tcp: fix dynamic right sizing
Dynamic Right Sizing (DRS) is supposed to open TCP receive window
automatically, but suffers from two bugs, presented by order
of importance.
1) tcp_rcv_space_adjust() fix :
Using twice the last received amount is very pessimistic,
because it doesn't allow fast recovery or proper slow start
ramp up, if sender wants to increase cwin by 100% every RTT.
copied = bytes received in previous RTT
2*copied = bytes we expect to receive in next RTT
4*copied = bytes we need to advertise in rwin at end of next RTT
DRS is one RTT late, it needs a 4x factor.
If sender is not using ABC, and increases cwin by 50% every rtt,
then we needed 1.5*1.5 = 2.25 factor.
This is probably why this bug was not really noticed.
2) There is no window adjustment after first RTT. DRS triggers only
after the second RTT.
DRS needs two RTT to initialize, so tcp_fixup_rcvbuf() should setup
sk_rcvbuf to allow proper window grow for first two RTT.
This patch increases TCP efficiency particularly for large RTT flows
when autotuning is used at the receiver, and more particularly
in presence of packet losses.

This patch series adds the support for configuring GMII_SEL register

the clock source for RMII phy mode whether to use internal clock or
the external clock from the phy itself.
Till now CPSW works as this configuration is done in U-Boot and carried
over to the kernel. But during suspend/resume Control module tends to
lose its configured value for GMII_SEL register in AM33xx PG1.0, so
if CPSW is used in RMII or RGMII mode, on resume cpsw is not working
as GMII_SEL register lost its configuration values.

drivers: net: cpsw-phy-sel: Add new driver for phy mode selection for cpsw
The cpsw currently lacks code to properly set up the hardware interface
mode on AM33xx. Other platforms might be equally affected.
Usually, the bootloader will configure the control module register, so
probably that's why such support wasn't needed in the past. In suspend
mode though, this register is modified, and so it needs reprogramming
after resume.
This patch adds a new driver in which hardware interface can configure
correct register bits when the slave is opened.
The AM33xx also has a bit for each slave to configure the RMII reference
clock direction. Setting it is now supported by a per-slave DT property.
This code path introducted by this patch is currently exclusive for
am33xx and same can be extened to various platforms via the DT compatibility
