2012-05-16Bluetooth: Fix skb length calculationGustavo Padovan
When we add a fragment to a skb, len and data_len fields need to be updated. Signed-off-by: Gustavo Padovan <gustavo@padovan.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2012-05-16Bluetooth: Fix packet size provided to the controllerGustavo Padovan
When building fragmented skb's skb->len keeps track of the size of head plus all fragments combined, however when queueing the skb for sending we need to report the head size instead of the total size, so we just set skb->len to skb_headlen(). This bug appeared when implementing MSG_MORE support for L2CAP sockets, it never showed up before because l2cap_skbuff_fromiovec() never accounted skb size correctly. A following patch will fix this.

2012-05-15tokenring: delete all remaining driver supportPaul Gortmaker
This represents the mass deletion of the of the tokenring support. It gets rid of: - the net/tr.c which the drivers depended on - the drivers/net component - the Kbuild infrastructure around it - any tokenring related CONFIG_ settings in any defconfigs - the tokenring headers in the include/linux dir - the firmware associated with the tokenring drivers. - any associated token ring documentation.

We are going to delete the Token ring support. This removes any special processing in the core networking for token ring, (aside from net/tr.c itself), leaving the drivers and remaining tokenring support present but inert. The mass removal of the drivers and net/tr.c will be in a separate commit, so that the history of these files that we still care about won't have the giant deletion tied into their history.
