Subject: bpf: fix error check.
X-Git-Tag: libpcap-1.10.2~203
X-Git-Url: https://git.tcpdump.org/libpcap/commitdiff_plain/a62db481c1eda725cf51b0ca991c8fea70df7b70?ds=sidebyside

bpf: fix error check.

The status of the bpf_bind() call, which is what might equal
BPF_BIND_BUFFER_TOO_BIG, is in status, not errno.

(cherry picked from commit b9428e2c4bcb4d8509a65b6fc9a4cb2ab23f3d1e)
