This patch changes the naming for interface private data for lowpan intefaces. The current private data scheme is: ------------------------------------------------- | 6LoWPAN Generic | LinkLayer 6LoWPAN | ------------------------------------------------- the current naming schemes are: - 6LoWPAN Generic: - lowpan_priv - LinkLayer 6LoWPAN: - BTLE - lowpan_dev - 802.15.4: - lowpan_dev_info the new naming scheme with this patch will be: - 6LoWPAN Generic: - lowpan_dev - LinkLayer 6LoWPAN: - BTLE - lowpan_btle_dev - 802.15.4: - lowpan_802154_dev Signed-off-by: Alexander Aring <aar@pengutronix.de> --- include/net/6lowpan.h | 6 +-- net/6lowpan/core.c | 8 ++-- net/6lowpan/debugfs.c | 22 +++++----- net/6lowpan/iphc.c | 38 +++++++++--------- net/6lowpan/nhc_udp.c | 2 +- net/bluetooth/6lowpan.c | 82 ++++++++++++++++++++------------------ net/ieee802154/6lowpan/6lowpan_i.h | 6 +-- net/ieee802154/6lowpan/core.c | 6 +-- net/ieee802154/6lowpan/tx.c | 14 +++---- 9 files changed, 94 insertions(+), 90 deletions(-)
