Michael Scott a4f4f6d6f3 net: net_if: avoid deref of NULL L2 ... When using offloaded network, an L2 is never assigned to the net_if. Only certain portions of the net_if code are referenced such as: net_if_up() net_if_down() And these functions make use of several L2 references: get_flags() enable() Let's add checks to make sure we don't deref a NULL when using these functions. Fixes the following exception on K64F and other HW which can make use of offloaded network HW: FATAL: ***** Reserved Exception ( -16) ***** FATAL: r0/a1: 0x00000010 r1/a2: 0x0000644f r2/a3: 0x00000000 FATAL: r3/a4: 0x00000000 r12/ip: 0x2000474c r14/lr: 0x0001475b FATAL: xpsr: 0x00000000 FATAL: Faulting instruction address (r15/pc): 0x0001b1cd FATAL: >>> ZEPHYR FATAL ERROR 0: CPU exception FATAL: Current thread: 0x20004c4c (unknown) Fixes: https://github.com/zephyrproject-rtos/zephyr/issues/18957 Signed-off-by: Michael Scott <mike@foundries.io>		2019-09-08 22:08:02 -04:00
