    [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctls · 88d3aafd

    For the operations
    	get-tx-csum
    	get-sg
    	get-tso
    	get-ufo
    the default ethtool_op_xxx behavior is fine for all drivers, so we
    permit op==NULL to imply the default behavior.
    
    This provides a more uniform behavior across all drivers, eliminating
    ethtool(8) "ioctl not supported" errors on older drivers that had
    not been updated for the latest sub-ioctls.
    
    The ethtool_op_xxx() functions are left exported, in case anyone
    wishes to call them directly from a driver-private implementation --
    a not-uncommon case.  Should an ethtool_op_xxx() helper remain unused
    for a while, except by net/core/ethtool.c, we can un-export it at a
    later date.
