net: mac802154: Explain the use of ieee802154_wake/stop_queue()

2022-01-28T10:23:41+00:00

It is not straightforward to the newcomer that a single skb can currently be sent at a time and that the internal process is to stop the queue when processing a frame before re-enabling it. Make this clear by documenting the ieee802154_wake/stop_queue() helpers.

ieee802154: cleanup WARN_ON for fc fetch

2016-07-08T11:23:12+00:00

This patch cleanups the WARN_ON which occurs when the sk buffer has insufficient buffer space by moving the WARN_ON into if condition. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

ieee802154: fix skb get fc on big endian

2016-07-08T11:23:12+00:00

This patch fixes ieee802154_get_fc_from_skb function on big endian machines. The function get_unaligned_le16 converts the byte order to host byte order but we want to keep the byte order like in mac header. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

ieee802154: 6lowpan: fix intra pan id check

2016-07-08T11:23:12+00:00

The RIOT-OS stack does send intra-pan frames but don't set the intra pan flag inside the mac header. It seems this is valid frame addressing but inefficient. Anyway this patch adds a new function for intra pan addressing, doesn't matter if intra pan flag or source and destination are the same. The newly introduction function will be used to check on intra pan addressing for 6lowpan. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

ieee802154: add ieee802154_skb_src_pan helper

This patch adds ieee802154_skb_src_pan function to get the pointer address of the source pan id at skb mac pointer. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann

mac802154: use put and get unaligned functions

2016-03-10T18:51:28+00:00

This patch removes the swap pointer and memmove functionality. Instead we use the well known put/get unaligned access with specific byte order handling. Signed-off-by: Alexander Aring Suggested-by: Marc Kleine-Budde Signed-off-by: Marcel Holtmann

mac802154: fix mac header length check

2016-02-23T19:29:39+00:00

I got report about that sometimes the WARN_ON occurs there which should never happen. I came to the conclusion that the mac header is there but inside the headroom of skb. The skb->len information doesn't contain the information about the headroom length and skb->len is lesser than two. We check now if the skb_mac_header pointer is set and the room between mac header pointer and tail pointer. Signed-off-by: Alexander Aring Signed-off-by: Marcel Holtmann
