From 2fc28de5989e1c40fee4e92e2a8f3bdd47b1b34a Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Thu, 10 May 2012 12:13:27 +0300 Subject: wlcore/wl18xx: add hw op for setting Tx HW checksum Some chip families are capable of checksumming certain classes of Tx packets in HW. Indicate this fact in the netdev features and perform the HW checksum by protocol type for the 18xx family. Fix the location of the skb network header when we move it so we can rely on it when setting the checksum.

When we moved the identify_chip operation to an earlier stage (ie. to the probe function), we broke wl127x support because during HW init we would set the WLCORE_QUIRK_TX_BLOCKSIZE_ALIGN. To avoid this, set this quirk in the identify_chip operations and only force it to be unset if the bus module doesn't support it. We were doing the opposite and setting the flag if the bus module supports it.

This is done by increasing the number of FEM manufacturers to 4. Usually FEM parameters from ini file are read from nvs file and passed to firmware using TEST_CMD_INI_FILE_RADIO_PARAM. Still, because the nvs file has only place for 2 FEMs, we need to pass the new FEM types information in one of the available entries. This is done by mapping new fem types 2,3 to entry 0. This solution works for manual FEM selection. AutoDetect-FEM still support only fem types 0 and 1.

Move the HT setting code down to allow the number of antennas to be set (and optionally overridden) before it. Remove the "mimo" HT option, since the default mode now enables MIMO is possible. Use this opportunity to add a helper function for setting HT capabilities and reduce the volume of the code a bit.

Since the read functions had no way of returning errors in-band, change their prototypes. Also rename prefixes of wlcore functions which their prototypes had to be changed.

The driver validates -- cgit v1.2.3 From 0fc1d2e9fe0820cc0c3247c5766c21b8de65a886 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Tue, 3 Jul 2012 11:34:43 +0300 Subject: wl12xx/wl18xx: use a dynamic PS timeout of 1.5sec It seems some parties have bad user experience when smaller values are used. This should have little implications for power consumption, since traffic is bursty in nature.
