[Qemu-commits] [COMMIT 3a179c6] Make net_client_init() consume slirp_co

Subject: [Qemu-commits] [COMMIT 3a179c6] Make net_client_init() consume slirp_configs even onerror
Date: Tue, 06 Oct 2009 20:05:40 -0000

From: Markus Armbruster <address@hidden>

net_slirp_init() walks slirp_configs, and stops when it encounters one
that doesn't work.  Instead of consuming slirp_configs members there,
consume them in the sole caller.  This makes sure all are consumed.
Before, the tail starting with the non-working one was left in place,
where it made the next net_slirp_init() fail again.
