iwl4965: better skb management in rx path

2013-12-04T18:57:36+00:00

commit c1de4a9557d9e25e41fc4ba034b9659152205539 upstream.

4965 version of Eric patch "iwl3945: better skb management in rx path".
It fixes several problems :

1) skb->truesize is underestimated.
   We really consume PAGE_SIZE bytes for a fragment,
   not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

iwl3945: better skb management in rx path

2013-12-04T18:57:36+00:00

commit 45fe142cefa864b685615bcb930159f6749c3667 upstream.

Steinar reported reallocations of skb->head with IPv6, leading to
a warning in skb_try_coalesce()

It turns out iwl3945 has several problems :

1) skb->truesize is underestimated.
   We really consume PAGE_SIZE bytes for a fragment,
   not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

iwlwifi: don't WARN on host commands sent when firmware is dead

2013-12-04T18:57:35+00:00

commit 8ca95995e64f5d270889badb3e449dca91106a2b upstream.

This triggers automatic bug reports and add no valuable
information. Print a simple error instead and drop the
host command.

prism54: set netdev type to "wlan"

2013-12-04T18:57:05+00:00

commit 8e3ffa471091c560deb6738ed9ab7445b7a5fd04 upstream.

Userspace uses the netdev devtype for stuff like device naming and type
detection.  Be nice and set it.  Remove the pointless #if/#endif around
SET_NETDEV_DEV too.

mwifiex: fix wrong eth_hdr usage for bridged packets in AP mode

2013-12-04T18:57:01+00:00

commit 8d93f1f309d38b65fce0b9f0de91ba6c96990c07 upstream.

The eth_hdr is never defined in this driver but it gets compiled
without any warning/error because kernel has defined eth_hdr.

Fix it by defining our own p_ethhdr and use it instead of eth_hdr.

mwifiex: correct packet length for packets from SDIO interface

2013-12-04T18:57:01+00:00

commit d03b4aa77e1187b77dfe37d14a923547f00baa66 upstream.

While receiving a packet on SDIO interface, we allocate skb with
size multiple of SDIO block size. We need to resize this skb
after RX using packet length from RX header.

rtlwifi: rtl8192cu: Fix incorrect signal strength for unassociated AP

2013-12-04T18:56:36+00:00

commit 78dbfecb95be4635b995af3bd29fa10013409fcd upstream.

The routine that processes received frames was returning the RSSI value for the
signal strength; however, that value is available only for associated APs. As
a result, the strength was the absurd value of 10 dBm. As a result, scans
return incorrect values for the strength, which causes unwanted attempts to roam.
