These wireless drivers in staging could be built when CONFIG_NET=n, CONFIG_NETDEVICES=n, causing this build error: net/wireless/wext-priv.c: In function 'ioctl_private_call': net/wireless/wext-priv.c:206: error: implicit declaration of function 'call_commit_handler' due to faulty selects.

Add txq_id info to "Tx queue requesting wakeup" debug message Add "Rx queue requesting wakeup" debug message Move clear of CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ to be after nearby iwl_write_prph(), since iwl_write_prph() sets it and clears it. Almost removed it entirely, but just making sure in case someone removes the iwl_write_prph()! Also remove unneeded priv->lock usage; this is now handled by priv->reg_lock within iwl_clear_bit(). Join a couple of lines that had unneeded line returns. Signed-off-by:

Follow-up to "update write pointers for all tx queues after wakeup"; that patch changed iwl_irq_tasklet_legacy(), but not iwl_irq_tasklet(), so newer devices were not covered. Comments from original patch: Wakeup interrupt has been updating write pointers (indexes, actually) only for tx queues 0-5. This is adequate just for 3945, but inadequate for other devices, all of which have more tx queues. Now updating all tx/command queues, so device can be aware of all new tx and host commands enqueued while device was asleep. This can potentially improve data traffic bandwidth and/or latency.

Take advantage of device's auto-increment for SRAM reads to eliminate extra write address accesses. Grab/release NIC access before/after entire read sequence, rather than for each read individually. After a quick check of dmesg logs, this seems to double Event Log dump speed, reducing from about 20 milliseconds to about 10 milliseconds for 512 entries using 3945. Signed-off-by:

Ben Cahill authored
If device provides bad values for Event Log parameters (due to being asleep or SRAM corruption, etc.), the size can be very, very large (e.g. 0xa5a5a5a5), which can flood system log. Sanity-check capacity and next_entry values and limit to reasonable size dump. Signed-off-by:

Different channel has different configuration, need to pass correct configuration to uCode when send "channel switch" command to uCode. Invalid configuration will cause sysassert in uCode and produce un-expected result. Even it is a very small windows, but we also need to consider and handle the case if commit_rxon occurred before the "channel switch announcement" notification received from uCode. Signed-off-by:

When I added that code setting the swq_id, I evidently did not understand the distinction between FIFO and TX queue yet and added code to compare a queue ID and a FIFO number, which is bogus. However, the code there need not be this specific, it can just set all queues to the identity mapping which will be overwritten by the aggregation queue code. As a bit of defensive coding, don't assign an swq_id to the command queue so that if we ever use it for frames we notice quickly. Signed-off-by:

Johannes Berg authored
The fourth queue (command queue) is already activated in the loop above that also maps it to the command FIFO and therefore doesn't need to be marked as activated again. Also change the TODO comment to be accurate -- we need to initialise the _queues_, not FIFOs, and map them to device FIFOs. Signed-off-by:

Do not mess with the original skb, but allocate an independent bouncebuffer. This protects against bad interference with mac80211's assumptions about the skb (which already caused bugs). Signed-off-by:

This patch rearranges the SIT DF bit handling using the new IPIP DF code. The only externally visible effect should be the case where PMTU is enabled and the MTU is exactly 1280 bytes. In this case the previous code would send packets out with DF off while the new code would set the DF bit. This is inline with RFC 4213. Signed-off-by:

Apparently, inet6_dump_addr() is not able to handle more than 64 ipv6 addresses per device. We must break from inner loops in case skb is full, or else cursor is put at the end of list. Signed-off-by:

Eric Dumazet authored
When handling large number of netdevice, inet6_dump_ifinfo() is very slow because it has O(N^2) complexity. Instead of scanning one single list, we can use the 256 sub lists of the dev_index hash table, and RCU lookups. Signed-off-by:
