mac802154: Drop IEEE802154_HW_RX_DROP_BAD_CKSUM

2022-10-12T10:57:19+00:00

This IEEE802154_HW_RX_DROP_BAD_CKSUM flag was only used by hwsim to reflect the fact that it would not validate the checksum (FCS). So this was only useful while the only filtering level hwsim was capable of was "NONE". Now that the driver has been improved we no longer need this flag.

net: mac802154: Bring the ability to hold the transmit queue

2022-06-10T07:48:40+00:00

Create a hold_txs atomic variable and increment/decrement it when relevant, ie. when we want to hold the queue or release it: currently all the "stopped" situations are suitable, but very soon we will more extensively use this feature for MLME purposes. Upon release, the atomic counter is decremented and checked. If it is back to 0, then the netif queue gets woken up. This makes the whole process fully transparent, provided that all the users of ieee802154_wake/stop_queue() now call ieee802154_hold/release_queue() instead. In no situation individual drivers should call any of these helpers manually in order to avoid messing with the counters. There are other functions more suited for this purpose which have been introduced, such as the _xmit_complete() and _xmit_error() helpers which will handle all that for them. One advantage is that, as no more drivers call the stop/wake helpers directly, we can safely stop exporting them and only declare the hold/release ones in a header only accessible to the core.

net: mac802154: Create an error helper for asynchronous offloading errors

2022-04-25T18:51:12+00:00

A few drivers do the full transmit operation asynchronously, which means that a bus error that happens when forwarding the packet to the transmitter or a timeout happening when offloading the request to the transmitter will not be reported immediately. The solution in this case is to call this new helper to free the necessary resources, restart the queue and always return the same generic TRAC error code: IEEE802154_SYSTEM_ERROR.

net: mac802154: Create an offloaded transmission error helper

2022-04-25T18:51:12+00:00

So far there is only a helper for successful transmissions, which led device drivers to implement their own handling in case of error. Unfortunately, we really need all the drivers to give the hand back to the core once they are done in order to be able to build a proper synchronous API. So let's create a _xmit_error() helper and take this opportunity to fill the new device-global field storing Tx statuses.

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

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
