    Subject[PATCH net-next 0/7] net: dsa: tagger simplification
    Date
    The DSA layer has a dsa_device_ops structure containing two members to
    tag and untag the proprietary switch header, called xmit and rcv.

    The switch tree and slave private structures respectively hold a useless
    copy of the rcv and xmit functions. The tagging implementations use
    useless goto labels and only the rcv caller (partially) handles the SKB
    freeing. The rcv function also contains unused arguments.

    This patchset removes the copy of rcv and xmit functions, the unused
    arguments of the rcv signature and the useless labels, and handles
    freeing of the SKB in the xmit caller.

    Vivien Didelot (7):
    net: dsa: hide dsa_uses_tagged_protocol code
    net: dsa: remove useless rcv copy in DSA tree
    net: dsa: remove unused arguments of tagger rcv
    net: dsa: free orig skb on rcv if reallocated
    net: dsa: remove useless goto label in tagger rcv
    net: dsa: remove useless copy of tagger xmit
    net: dsa: factor skb freeing on xmit
