arp-scan 1.5.1 works on Solaris 10, but fails on Solaris 11. It is believed that this is due to the new "vanity names" for network devices that were introduced with Solaris 11 not working with DLPI.

This is not considered to be a major issue, as Solaris is rarely seen nowadays. However, if this is causing you a problem, please comment against this issue and I will investigate further.

Added check for pointer returned by link_open and die with an error if it's NULL in commit 36de712

This doesn't solve the problem, but provides a better error message than receiving a SIGSEGV due to a null pointer dereference.

Example output on Solaris 11 is:

root@solaris11:~/arp-scan# ./arp-scan --localnet ERROR: cannot open interface net0 with DLPI

This issue won't be worked on unless someone comments, because I don't think Solaris is an important platform any more. So please comment if you care about this issue.
