Miller" , netdev@vger.kernel.org, linux-hams@vger.kernel.org AX.25, NET/ROM and ROSE unfortunately still use jiffies as the unit of time for all their timeouts that can be configured through sysctl and it's procfs equivalents. This did result in a change of these kernel interfaces going from Linux 2.4 to 2.6 for anybody who was unlucky enough to use an affected platform such as i386 and most MIPS but not Alpha. Making matters worse, it required the sysadmin of the particular system to know the timing value making it very, very broken inteface design. The timer interrupt frequency recently becoming configurable made things even worse, so this really needed to be fixed. The following series of patches contains three patches, one for each of the three packet radio protocols to switch the unit used by the sysadmin to miliseconds thus resulting in a deterministic interface.
