Provide a kernel-doc comment documentation for the BQL helpers: - netdev_sent_queue - netdev_completed_queue - netdev_reset_queue Similarly to how it is done for the other functions, the documentation only covers the function operating on struct net_device and not struct netdev_queue. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> --- Change since v1: - incorporate suggestsions from Eric Dumazet and just specify the exact match for netdev_sent_queue/netdev_completed_queue include/linux/netdevice.h | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+)
