This patch adds support for handling BA request and BA setup events for AP interface. RA list is marked as either 11n enabled or disabled from station's capabilities in association request. BA setup is initiated only after some specific number of packets for particular RA list are transmitted. Signed-off-by:

1. Separate file for uAP RX handling. 2. If received packet is broadcast/multicast, send it to kernel as well as requeue it back to uAP TX queue. 3. If received packet is for associated STA (intra-BSS), requeue it back to uAP TX queue. 4. In all other cases (packets for AP or inter-BSS packets), pass packet to kernel to handle it accordingly.

After station is associated an entry would be added to station list. This entry would have station specific information such as 11n support, AMSDU size. The entry would be deleted after deauthentication. All station entries would be deleted during BSS_IDLE event. Signed-off-by:

Earlier scan command was postponed by 20msec multiple times to give preference to Tx traffic until we find empty wmm queue. There is a corner case in which wmm queue becomes empty immediately after processing the packet(before 20msec) and there may be next packet coming after some time. In this case we should not resume scan operation. We will use new flag to check Tx traffic and resume scan operation only if there is no traffic for 200msec. Signed-off-by:

As per recent patch "658f37b7 mwifiex: scan less channels..." less channels are scanned per scan command in associated state. Default number of channels per scan command for normal scan are already 4, but those are 14 for SSID specific scan operation. This code change in this patch is required for SSID specific scan.

We do similar conversion for Tx packet header but it was missing for Rx packet header. Without this fix, Rx packet header won't be correctly parsed on big endian platform. Signed-off-by:

Padding arithmetic will always work for MSDUs provided first MSDU ends on 4-byte boundary. Fixing it by making sure that all MSDU ends on 4-byte boundary. Signed-off-by:

Since commit: fb3c19bc, adding extra padding to AMSDU is redundant since same is being performed at mwifiex_11n_aggregate_pkt after forming the AMSDU packet. Fixing it by removing it. Signed-off-by:

All MSDU subframes, except the first one in AMSDU, were being written wrongly at the location of first MSDU frame. Fixing that by copying the MSDU at skb->tail of AMSDU. Signed-off-by:

This patch contains following modifications: - Add mesh capabilities on fw.c to permit creation of mesh interfaces using this driver. - Modify carl9170_set_operating_mode, to use AP-style beaconing with mesh interfaces. - Allow beacon updates for NL80211_IFTYPE_MESH_POINT type in carl9170_handle_command_response. - Add NL80211_IFTYPE_MESH_POINT case on carl9170_op_add_interfaces to support mesh/ap/sta virtual interface combinations.

First of all, use PHY names instead of magic numbers. It should make configuring kernel easier in case of not enabled PHY type support. Secondly, always print info about PHY. This is really basic info about hardware and quite important for the support level. Signed-off-by:

Drivers that load firmware from their probe routine have problems with the latest versions of udev as they get timeouts while waiting for user space to start. The problem is fixed by using request_firmware_nowait() and delaying the start of mac80211 until the firmware is loaded. To prevent the possibility of the driver being unloaded while the firmware loading callback is still active, a completion queue entry is used. Signed-off-by:

When a device is unregistered, we have to purge all of the references to it that may exist in the entire system. If a route is uncached, we currently have no way of accomplishing this. So create a global list that is scanned when a network device goes down. This mirrors the logic in net/core/dst.c's dst_ifdown(). Signed-off-by:David S. Miller <davem@davemloft.net>

Input path is mostly run under RCU and doesnt touch dst refcnt But output path on forwarding or UDP workloads hits badly dst refcount, and we have lot of false sharing, for example in ipv4_mtu() when reading rt->rt_pmtu Using a percpu cache for nh_rth_output gives a nice performance increase at a small cost. 24 udpflood test on my 24 cpu machine (dummy0 output device) (each process sends 1.000.000 udp frames, 24 processes are started) before : 5.24 s after : 2.06 s For reference, time on linux-3.5 : 6.60 s Signed-off-by:

commit 404e0a8b (net: ipv4: fix RCU races on dst refcounts) tried to solve a race but added a problem at device/fib dismantle time : We really want to call dst_free() as soon as possible, even if sockets still have dst in their cache. dst_release() calls in free_fib_info_rcu() are not welcomed. Root of the problem was that now we also cache output routes (in nh_rth_output), we must use call_rcu() instead of call_rcu_bh() in rt_free(), because output route lookups are done in process context. Based on feedback and initial patch from David Miller (adding another call_rcu_bh() call in fib, but it appears it was not the right fix) I left the inet_sk_rx_dst_set() helper and added __rcu attributes to nh_rth_output and nh_rth_input to better document what is going on in this code.

commit c6cffba4 (ipv4: Fix input route performance regression.) added various fatal races with dst refcounts. crashes happen on tcp workloads if routes are added/deleted at the same time. The dst_free() calls from free_fib_info_rcu() are clearly racy. We need instead regular dst refcounting (dst_release()) and make sure dst_release() is aware of RCU grace periods : Add DST_RCU_FREE flag so that dst_release() respects an RCU grace period before dst destruction for cached dst Introduce a new inet_sk_rx_dst_set() helper, using atomic_inc_not_zero() to make sure we dont increase a zero refcount (On a dst currently waiting an rcu grace period before destruction) rt_cache_route() must take a reference on the new cached route, and release it if was not able to install it. With this patch, my machines survive various benchmarks. Signed-off-by:

early_demux() handlers should be called in RCU context, and as we use skb_dst_set_noref(skb, dst), caller must not exit from RCU context before dst use (skb_dst(skb)) or release (skb_drop(dst)) Therefore, rcu_read_lock()/rcu_read_unlock() pairs around ->early_demux() are confusing and not needed : Protocol handlers are already in an RCU read lock section. (__netif_receive_skb() does the rcu_read_lock() ) Signed-off-by:
