Module Name:    src
Committed By:   msaitoh
Date:           Mon Nov  7 08:32:35 UTC 2022

Modified Files:
        src/sys/net: if_dl.h

Log Message:
Increase sdl_data so that more then IFNAMSIZ bytes are available (again).

COMPAT_9 is not required.

 - The getifaddrs(3) function has no problem. The routing message has no
   problem because struct rtm_msglen has rtm_msglen and we can get the next
   message using with it. There is no any kernel data structure which has
   struct sockaddr_dl foobadr[xxx] array.

 - A data passed from userland and a kernel data are compared with
   sockaddr_cmp(). The return value is used to check if the size is
   inadequate or not.

 - In the kernel, sdl_len is not directly used for the length of memcpy()
   but the sockaddr_dl_measure() is used for it.
