* bpf: remove struct bpf_prog_type_listJohannes Berg2017-04-115-122/+44
| | | | | | | | | | | | | | | | | | There's no need to have struct bpf_prog_type_list since it just contains a list_head, the type, and the ops pointer. Since the types are densely packed and not actually dynamically registered, it's much easier and smaller to have an array of type->ops pointer. Also initialize this array statically to remove code needed to initialize it. In order to save duplicating the list, move it to a new header file and include it in the places needing it.

|/ | | | | | | | | | | | | There's no point in checking for duplicate sessions at the beginning of l2tp_nl_cmd_session_create(); the ->session_create() callbacks already return -EEXIST when the session already exists. Furthermore, even if l2tp_session_find() returns NULL, a new session might be created right after the test. So relying on ->session_create() to avoid duplicate session is the only sane behaviour.

This one tackles the TX path of the driver. This provides the bulk of the performance improvements by adding support for fragmented sends along with a bunch of cleanups. Version 2 fixes a patch splitting mistake and uses eth_skb_pad() (which uses skb_put_padto) to pad ethernet frames rather than skb_padto(), thus removing the need to also pad the packet headlen in a couple of places. Subsequent batches will add various features (ethtool functions, vlan offlan, ...) and cleanups. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a private lock which isn't terribly useful, and we maintain a "tx_pending" counter for information that's already available via a trivial arithmetic operation. Then we unconditionaly wake the queue even when not stopped. Finally our code in tx isn't really safe vs. a concurrent reclaim. The aspeed chips aren't SMP today but I prefer the code being right and future proof. So rip that out and replace it with more "standard" queue handling, currently with a threshold of 1 queue element, which will be increased when we implement fragmented sends.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The larger the bt a2dp bit pool is, the more time bt needs to receive them. If we do not adjust the wifi duration, the voice quality will be low. Hence we reduce the time that wifi holds, to improve the a2dp service.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For wifi and bt coexistence, if the aggregation size of wifi is too large, the transmission time of the aggregated packet could be too long and the bt packets might "cut off" the wifi packet. We need to reduce the aggregation size to improve wifi performance.
