Yuck.

Please try the attached patch.

Subject: [PATCH] sundance: SIOCDEVPRIVATE pollution
To quote one of my favorite contemporary author:
[include/linux/sockios.h]
* THESE IOCTLS ARE _DEPRECATED_ AND WILL DISAPPEAR IN 2.5.X -DaveM
*/
#define SIOCDEVPRIVATE 0x89F0 /* to 89FF */
[...]
Gentoo's snmpd trips up over this code when trying to figure if the
driver supports the non-SIOCDEVPRIVATE API or not. One can argue over
its choice of heuristic but there no reason to make ioctl more ugly
than needed.
