Subject: Revert "Do the same tests for "not supported" SIOCGIFMEDIA as is done elsewhere."
X-Git-Tag: libpcap-1.10-bp~634
X-Git-Url: https://git.tcpdump.org/libpcap/commitdiff_plain/03225d646ab497de105032aeda22270a5b8293f7

Revert "Do the same tests for "not supported" SIOCGIFMEDIA as is done elsewhere."

This reverts commit 0853992857112d8a1dbc4deae22c488a155eb73b.

Those tests are necessary only with one networking driver on macOS; that
code isn't used in macOS.
