Subject: promisc: Constify `ifname' parameters to {enter,leave}_promiscuous_mode()
X-Git-Tag: v0.5.8-rc3~22
X-Git-Url: https://repo.or.cz/w/netsniff-ng.git/commitdiff_plain/af0c1f5f89750f16054c988937e180764c411c20

promisc: Constify `ifname' parameters to {enter,leave}_promiscuous_mode()

The parameter `ifname' to {enter,leave}_promiscuous_mode() is never
modified inside the functions, thus mark it as const.
