[PATCH] mac80211: Clear beacon_int in ieee80211_do_stop

From: Ben Greear This fixes stale beacon-int values that would keep a netdev from going up. To reproduce: Create two VAP on one radio. vap1 has beacon-int 100, start it. vap2 has beacon-int 240, start it (and it will fail because beacon-int mismatch). reconfigure vap2 to have beacon-int 100

[PATCH] mac80211: Improve connection-loss probing.

From: Ben Greear This makes the mlme code probe multiple times spread out across the time-out period instead of lots of probes all at once. It also makes the ap-probe and the nullfunc probe logic act similarly, which allows us to remove some code. Signed-off-by: Ben Greear ---

[PATCH v2 12/21] ath10k: Support up to 64 vdevs.

From: Ben Greear The (1 << x) - 1 trick won't work when you are trying to fill up all 64 bits, so add special case for that. And, move the limits to the per-nic structure instead of per-driver to allow better dynamic use of the limits. Signed-off-by: Ben Greear

[PATCH] mac80211: Get ethtool-stats frequency more often.

From: Ben Greear Some NICs (ath9k_htc) don't use chanctx_conf, it seems, so look at local->hw.conf.channel->center_freq in that case. Signed-off-by: Ben Greear --- net/mac80211/ethtool.c | 12 1 file changed, 8 insertions(+), 4

[PATCH 09/21] ath10k: print fw debug messages in hex.

From: Ben Greear This allows user-space tools to decode debug-log messages by parsing dmesg or /var/log/messages. Signed-off-by: Ben Greear --- drivers/net/wireless/ath/ath10k/debug.c | 72 +

[PATCH 07/21] ath10k: save firmware RAM and ROM BSS sections on crash

From: Ben Greear This can be used to get a useful back trace out of a firmware crash that involves an interrupt handler. For instance, a null-pointer-exception would be this kind of trace. A user-space tool can read the debugfs file and decode things as wished. This

[PATCH 08/21] ath10k: make firmware text debug messages more verbose.

From: Ben Greear There are not many of these messages producted by the firmware, but they are generally fairly useful, so print them at info level. Signed-off-by: Ben Greear --- drivers/net/wireless/ath/ath10k/wmi.c | 2 +- 1 file changed, 1

[PATCH 04/21] ath10k: rate-limit packet tx errors

From: Ben Greear When firmware crashes, stack can continue to send packets for a bit, and existing code was spamming logs. So, rate-limit the error message for tx failures. Signed-off-by: Ben Greear --- drivers/net/wireless/ath/ath10k/mac.c |

[PATCH 10/21] ath10k: support logging ath10k_info as KERN_DEBUG

From: Ben Greear Helps keep messages off of (serial) console when that is desired. Signed-off-by: Ben Greear --- drivers/net/wireless/ath/ath10k/debug.c | 5 - drivers/net/wireless/ath/ath10k/debug.h | 6 ++ 2 files changed, 10

[PATCH 18/21] ath10k: Note limitation on beaconing vdevs.

From: Ben Greear This only pertains to CT firmware, as standard firmware can't do anywhere near this many vdevs anyway. Signed-off-by: Ben Greear --- drivers/net/wireless/ath/ath10k/mac.c | 16 1 file changed, 16 insertions(+)

[PATCH 05/21] ath10k: save firmware debug log messages.

[PATCH 06/21] ath10k: save firmware stacks upon firmware crash

From: Ben Greear Should help debug firmware crashes, and give users a way to provide some useful debug reports to firmware developers. Signed-off-by: Ben Greear Signed-off-by: Kalle Valo ---

[PATCH 21/21] ath10k: Read dbglog buffers over register ping-pong.

From: Ben Greear This gives much better debugging capability when debugging crashes in the firmware that cause CE transport loss. (Such as AXI errors). Signed-off-by: Ben Greear --- drivers/net/wireless/ath/ath10k/pci.c | 47

[PATCH 20/21] ath10k: read firmware crash over ioread32 if CE fails.

From: Ben Greear This might work around problem where sometimes host cannot access firmware crash over normal CE transport. Requires CT firmware with matching logic in it's assert handler (-13 and higher releases). Signed-off-by: Ben Greear

[PATCH 16/21] ath10k: Support 32+ stations.
