Merge branch 'stmmac-fixes' 

Ong Boon Leong says:

====================
net: stmmac: general fixes for Ethernet functionality

1/5: It ensures that the previous value of GMAC_VLAN_TAG register is
     read first before for updating the register.

2/5: Similar to 2/6 patch but it is a fix for XGMAC_VLAN_TAG register
     as requested by Jose Abreu.

3/5: It ensures the GMAC IP v4.xx and above behaves correctly to:-
       ip link set <devname> multicast off|on

4/5: Added similar IFF_MULTICAST flag for xgmac2, similar to 4/6.

5/5: It ensures PCI platform data is using plat->phy_interface.

Changes from v4:-
   patch 1/6 - this patch is dropped now and will take the input on
               handling return value from netif_set_real_num_rx|
               tx_queues() in future patch series.

v3:-
   patch 1/6 - add rtnl_lock() and rtnl_unlock() for stmmac_hw_setup()
               called inside stmmac_resume()
   patch 3/6 - Added new patch to fix XGMAC_VLAN_TAG register writting

v2:-
   patch 1/5 - added control for rtnl_lock() & rtnl_unlock() to ensure
               they are used forstmmac_resume()
   patch 4/5 - added IFF_MULTICAST flag check for xgmac to ensure
               multicast works correctly.

v1:-
 - Drop v1 patches (1/7, 3/7 & 4/7) that are not valid.
