From: Ursula Braun-Krahl From: Thomas Spatzier From: Peter Tiedemann network driver changes. - iucv: add missing symbolic links between /sys/bus/iucv/drivers/netiucv and /sys/class/net. - iucv: make use of the debug feature. - iucv: 0 vs. NULL cleanup, avoid build warnings. - iucv: remove unnecessary -ENODEV check after call to iucv_declare_buffer. - ctc: adjust debug feature log levels. - lcs: replace broken schedule_timeout call with msleep. - qeth: add missing link type. - qeth: treat add_hhlen attribute as decimal value.
