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. ==================== Signed-off-by: David S.
