6lowpan: Don't set IFF_NO_QUEUE

2017-04-12T20:02:40+00:00

There is no point in setting IFF_NO_QUEUE should already have taken
care of setting it if tx_queue_len is not set, in fact this may
actually disable queue for interfaces that require it and do set
tx_queue_len.

6lowpan: Use netdev addr_len to determine lladdr len

2017-04-12T20:02:36+00:00

This allow technologies such as Bluetooth to use its native lladdr which
is eui48 instead of eui64 which was expected by functions like
lowpan_header_decompress and lowpan_header_compress.

6lowpan: iphc: override l2 packet information

2017-04-12T20:02:36+00:00

The skb->pkt_type need to be set by L2, but on 6LoWPAN there exists L2
e.g. BTLE which doesn't has multicast addressing. If it's a multicast or
not is detected by IPHC headers multicast bit. The IPv6 layer will
evaluate this pkt_type, so we force set this type while uncompressing.
Should be okay for 802.15.4 as well.

6lowpan: Set MAC address length according to LOWPAN_LLTYPE

2017-04-12T20:02:36+00:00

Set MAC address length according to the 6LoWPAN link layer in use.

6lowpan: use rb_entry()

2017-01-22T21:46:13+00:00

To make the code clearer, use rb_entry() instead of container_of() to
deal with rbtree.

6lowpan: ndisc: no overreact if no short address is available

2016-09-19T18:19:34+00:00

This patch removes handling to remove short address for a neigbour entry
if RS/RA/NS/NA doesn't contain a short address. If these messages
doesn't has any short address option, the existing short address from
ndisc cache will be used. The current behaviour will set that the
neigbour doesn't has a short address anymore.

6lowpan: ndisc: set invalid unicast short addr to unspec

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

When receiving neighbour information with short address option field we
should check the complete range of invalid short addresses and set it to
one invalid address setting which is the unspecified address. This
address is also used when by creating at first a new neighbour entry to
indicate no short address is set.
