Subject: [5/6] alx: fix MAC address alignment problem
Origin: https://git.kernel.org/cgit/linux/kernel/git/davem/net-next.git//commit?id=46ab9b347d677976b2b4072837cb4065839c0b80
In two places, parts of MAC addresses are used as u32/u16
values. This can cause alignment problems, use put_unaligned
and get_unaligned to fix this.

Subject: [6/6] alx: fix ethtool support code
Origin: https://git.kernel.org/cgit/linux/kernel/git/davem/net-next.git//commit?id=7ec5689461989fd80f1cf82ae084f5d50a5e63ee
A number of places treated features wrongly, listing not-supported
features instead of supported ones. Also, the get_drvinfo ethtool
callback isn't needed, and alx_get_pauseparam can be simplified.

current link speed and duplex setting.

Subject: [1/6] alx: treat flow control correctly in alx_set_pauseparam()
Origin: https://git.kernel.org/cgit/linux/kernel/git/davem/net-next.git//commit?id=ef0cc4b1d296ce041e3b24d103177dd70642740c
Even when alx_setup_speed_duplex() is called, we still
need to call alx_cfg_mac_flowcontrol() and set hw->flowctrl
if flow control changed.
This was a bug I accidentally introduced while simplifying
the original driver.
