Staging: add rtl8187se driver
This is a driver for the Realtek 8187 "SE" wireless PCI devices in some netbook computers (MSI Wind, and others). It includes its own copy of the ieee80211 stack, but it is compiled into the driver to prevend duplicate symbol issues. This version comes from Ralink with no authorship, but it is based on an old version of the rtl8180 driver from Andrea Merello. It was hacked up a bit to get it to build properly within the kernel tree and to properly handle the merged wireless stack within the driver. Cc: Andrea Merello <andreamrl@tiscali.it> Cc: linux-wireless <linux-wireless@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

121In the event that fragmentation is required, the incoming payload is split into
122N parts of size ieee->fts. The first fragment contains the SNAP header and the
123remaining packets are just data.
124
125If encryption is enabled, each fragment payload size is reduced by enough space
126to add the prefix and postfix (IV and ICV totalling 8 bytes in the case of WEP)
127So if you have 1500 bytes of payload with ieee->fts set to 500 without
128encryption it will take 3 frames. With WEP it will take 4 frames as the
129payload of each frame is reduced to 492 bytes.

18 Some ideas borrowed from the 8139too.c driver included in linux kernel.
19
20 We (I?) want to thanks the Authors of those projecs and also the
21 Ndiswrapper's project Authors.
22
23 A big big thanks goes also to Realtek corp. for their help in my attempt to
24 add RTL8185 and RTL8225 support, and to David Young also.

17 understand some things and gets some ideas
18
19 Code from rtl8181 project has been useful to me to understand some things.

21 Some code from 'Deuce' work

23 We want to tanks the Authors of such projects and the Ndiswrapper
