Adds 4.4BSD IP alias compatibility to SIOCGIFADDR, SIOCGIFBRDADDR, SIOCGIFDSTADDR, SIOCGIFNETMASK ioctls. 4.4BSD-compatible IP aliases can be configured since Linux 2.2 with "ip addr add ...". Version: 2. Changed to try (name,address) search only in response to the four ioctls mentioned above. Thanks to Alexey Kuznetsov for finding this. Merged: 2001-09-18: 2.4.9-ac12, 2001-10-01: 2.4.11-pre2.
The same as linux-2.4.9-devinet.c.patch, backported to 2.2.19.
