      net: vlan: add 802.1ad support · 8ad227ff
      Patrick McHardy authored
      
      
      Add support for 802.1ad VLAN devices. This mainly consists of checking for
      ETH_P_8021AD in addition to ETH_P_8021Q in a couple of places and check
      offloading capabilities based on the used protocol.
      
      Configuration is done using "ip link":
      
      # ip link add link eth0 eth0.1000 \
      	type vlan proto 802.1ad id 1000
      # ip link add link eth0.1000 eth0.1000.1000 \
      	type vlan proto 802.1q id 1000
      
      52:54:00:12:34:56 > 92:b1:54:28:e4:8c, ethertype 802.1Q (0x8100), length 106: vlan 1000, p 0, ethertype 802.1Q, vlan 1000, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84)
          20.1.0.2 > 20.1.0.1: ICMP echo request, id 3003, seq 8, length 64
      92:b1:54:28:e4:8c > 52:54:00:12:34:56, ethertype 802.1Q-QinQ (0x88a8), length 106: vlan 1000, p 0, ethertype 802.1Q, vlan 1000, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 47944, offset 0, flags [none], proto ICMP (1), length 84)
          20.1.0.1 > 20.1.0.2: ICMP echo reply, id 3003, seq 8, length 64

      net: vlan: rename NETIF_F_HW_VLAN_* feature flags to NETIF_F_HW_VLAN_CTAG_* · f646968f
      Patrick McHardy authored
      
      
      Rename the hardware VLAN acceleration features to include "CTAG" to indicate
      that they only support CTAGs. Follow up patches will introduce 802.1ad
      server provider tagging (STAGs) and require the distinction for hardware not
      supporting acclerating both.

      v4 GRE: Add TCP segmentation offload for GRE · 68c33163
      Pravin B Shelar authored
      
      
      Following patch adds GRE protocol offload handler so that
      skb_gso_segment() can segment GRE packets.
      SKB GSO CB is added to keep track of total header length so that
      skb_segment can push entire header. e.g. in case of GRE, skb_segment
      need to push inner and outer headers to every segment.
      New NETIF_F_GRE_GSO feature is added for devices which support HW
      GRE TSO offload. Currently none of devices support it therefore GRE GSO
      always fall backs to software GSO.
