2011-08-25af-packet: TPACKET_V3 flexible buffer implementation.chetan loke1-46/+891
1) Blocks can be configured with non-static frame-size. 2) Read/poll is at a block-level(as opposed to packet-level). 3) Added poll timeout to avoid indefinite user-space wait on idle links. 4) Added user-configurable knobs: 4.1) block::timeout. 4.2) tpkt_hdr::sk_rxhash. Changes: C1) tpacket_rcv() C1.1) packet_current_frame() is replaced by packet_current_rx_frame() The bulk of the processing is then moved in the following chain: packet_current_rx_frame() __packet_lookup_frame_in_block fill_curr_block() or retire_current_block dispatch_next_block or return NULL(queue is plugged/paused) Signed-off-by: Chetan Loke <loke.chetan@gmail.com> Signed-off-by: David S.

2011-08-25IEEE802.15.4: 6LoWPAN basic supportAlexander Smirnov4-3/+1108
This patch provides base support for transmission of IPv6 packets as well as the formation of IPv6 link-local addresses and statelessly autoconfigured addresses on top of IEEE 802.15.4 networks. For more information please look at the RFC4944 "Compression Format for IPv6 Datagrams in Low Power and Losst Networks (6LoWPAN).

There is a possibility of be_post_rx_frags() being called simultaneously from both be_worker() (when rx_post_starved) and be_poll_rx() (when rxq->used is 0).
