To: linux-wireless; +Cc: bjd, dbrownell, netdev
Split up rndis_host.c into rndis_host.h and rndis_base.c. This is done so
that rndis_wext can reuse common parts with rndis_host.

Hello,
Here is the third try on wireless RNDIS patchset.
Patches 1-9 are from second patchset (with name change rndis_wext -> rndis_wlan
in comments where needed):
1. Fix sparse warning: returning void valued expression
2. [cdc_ether] Hardwire CDC descriptors when missing
3. [rndis_host] Use 1KB buffer in rndis_unbind
4. [rndis_host] Halt device if rndis_bind fails
5. [rndis_host] Fix rndis packet filter flags
6. [usbnet] Use wlan device name for RNDIS wireless devices
7. [rndis_host] Split up rndis_host.c
8. [rndis_host] export functions
9. [usbnet] add driver_priv pointer to 'struct usbnet'
Changed patches 10-14:
10. [rndis_host] Add early_init function pointer to 'struct rndis_data'.
11. [rndis_host] Add link_change function pointer to 'struct rndis_data'.
12. [rndis_host] Add RNDIS physical medium checking into generic_rndis_bind()
13. Move usbnet.h and rndis_host.h to include/linux/usb
14. Add new driver 'rndis_wlan' for wireless RNDIS devices.
Devices are now detected by RNDIS physical medium type instead of
vendor/product ids. Driver has new infrastucture/authentication/encryption
setup code (from ndiswrapper) which fixes issued with WEP and AdHoc.
List of modes I've tested and work:
- WEP
- WPA2 PSK (with CCMP)
- unencrypted
- unencrypted ad-hoc
- hidden unencrypted
- ad-hoc WEP
- hidden WEP
That do not work:
- WPA PSK (with TKIP), I couldn't get this work with Windows driver using
ndiswrapper and driver from previous patchset and no call were made
to driver with SIOCSIWENCODEEXT so I'm starting to think problem is with
the version of wpa_supplicant I have.
- Hidden WPA, didn't work with earlier driver and as far as I know ndiswrapper
has the same problem.
Untested:
- WPA PSK with CCMP
- WPA2 PSK with TKIP
- WPA/WPA2 Enterprise
Patches should be applied in order, series apply cleanly to 2.6.24-git1.
