[PATCH v4 0/4] Handling extended headers of bnep control frames

[Grzegorz Kolodziejczyk <grzegorz.kolodziejczyk@tieto.com>]

This patch set adds support for handling extended headers of bnep control
frames which is mandatory. Until now extended headers for control messages was
ignored.

Patch [1/4] adds setting of err variable if control message is not understood.
Patch [2/4] adds additional ioctl for get supported bnep features. This is
needed for user space to know if handling of sending success setup response
frame should be handled by kernel or by user space.
Patch [3/4] adds support for handling extended headers of bnep control frames.
Patch [4/4] adds support for handling connection setup request.

Patch set tested with PTS bnep test cases. No regression, issues found during
testing.

v2.
- Added ioctl definition to compat_ioctl,
- Distinct bnep session flags and bnep features.

v3.
- Splited extended header, connection setup request handling into separated
	patches,
- Fixed flags, supported features defines as Marcel pointed,
- Extended commit messages,
- Remove copying flags from us to kernel bnep session,
- Fix setting bnep session bits as Marcel pointed.

v4.
- Unify internal/us flags usage like in HIDP, CMTP,
- Refactor send setup response as Marcel suggested,
- Make supported feature variable as local ioctl variable and set it while
adding session if required.
