Change Details

The code incorrect accessed user memory directly. Expose and use ifr_buffer_get_(buffer|length) APIs to access the ifreq buffer and allowing freebsd32 support.

Check copyin's error code (differ adding copyout checks at this time). Don't directly access user memory in the switch statement. Since bnxt_ioctl_data isn't all that big, use a stack allocation.
