Infineon(now Intel) HSPA Modem platform NCM cannot support ARP. we can define a new common structure wwan_noarp_info. Then more similiar NO ARP devices can be handled easily Signed-off-by: Wei Shuai <redacted> --- drivers/net/usb/cdc_ncm.c | 21 +++++++++++++++++++++ 1 files changed, 21 insertions(+), 0 deletions(-)
