Merge branch 'hns-phy-loopback'
Lin Yun Sheng says:
====================
Add loopback support in phy_driver and hns ethtool fix
This Patch Set add set_loopback in phy_driver and use it to setup loopback
when doing ethtool phy self_test.
Patch V8:
Respin the Patch based on net-next
Patch V7:
1. Add comment why resume the phy in hns_nic_config_phy_loopback.
2. Fix a typo error in patch description.
Patch V6:
Fix Or'ing error code in __lb_setup.
Patch V5:
Removing non loopback related code change.
Patch V4:
1. Remove c45 checking
2. Add -ENOTSUPP when function pointer is null,
take mutex in phy_loopback.
Patch V3:
Calling phy_loopback enable and disable in pair in hns mac driver.
Patch V2:
1. Add phy_loopback in phy_device.c.
2. Do error checking and do the read and write once in
genphy_loopback.
3. Remove gen10g_loopback in phy_device.c.
Patch V1:
Initial Submit
