* wireless: Remove unnecessary alloc/OOM messages, alloc cleanupsJoe Perches2013-02-041-4/+1
| | | | | | | | | | | | | | alloc failures already get standardized OOM messages and a dump_stack. Convert kzalloc's with multiplies to kcalloc. Convert kmalloc's with multiplies to kmalloc_array. Remove now unused variables. Remove unnecessary memset after kzalloc->kcalloc. Whitespace cleanups for these changes. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

* mwifiex: rx path enhancement to derive priv only onceAvinash Patil2012-10-291-5/+3
| | | | | | | | | | | We derive mwifiex_private structure which is per interface from received skb's rx_info. Once priv is derived, same priv can be propagated to other functions instead of callee deriving priv from rx_info again.

* mwifiex: add 11n Block Ack support for uAPAvinash Patil2012-08-061-4/+11
| | | | | | | | | | | | | | | 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.

| * mwifiex: fix 11n rx packet drop issueStone Piao2012-06-221-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we check the sequence number of last packet received against start_win. If a sequence hole is detected, start_win is updated to next sequence number. Since the rx sequence number is initialized to 0, a corner case exists when BA setup happens immediately after association. As 0 is a valid sequence number, start_win gets increased to 1 incorrectly. This causes the first packet with sequence number 0 being dropped. Initialize rx sequence number as 0xffff and skip adjusting start_win if the sequence number remains 0xffff. The sequence number will be updated once the first packet is received.

* | wireless: Remove casts to same typeJoe Perches2012-06-061-13/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p Neatened the mwifiex_deauthenticate_infra function which was doing odd things with array pointers and not using is_zero_ether_addr.
