Subject: mISDN: Add E-Channel logging features
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1f28fa19d34c0d9186f274e61e4b3dcfc6428c5c;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

mISDN: Add E-Channel logging features

New prim PH_DATA_E_IND.

 - all E-ch frames are indicated by recv_Echannel(), which pushes E-Channel
   frames into dch's rqueue
 - if dchannel is opened with channel nr 0, no E-Channel logging
   is requested
 - if dchannel is opened with channel nr 1, E-Channel logging
   is requested. if layer1 does not support that, -EINVAL
   in return is appropriate
