* soloscli: allow user to apply settings to solos h/w before bringing up ↵Felix Fietkau2011-02-131-0/+15
network (patch by Philip Prindeville) If the network/wan configuration contains "solos0" ... "solos3" then this list of strings will be applied to the FPGA when the hardware is hotplug added. The syntax should be "tag=value", as per the values enumerated in the solos-attr.c list. In the canned example, the modem is temporarily turned off, told to detect noise, told to disable annexes M and A (effectively putting it into pure ADSL mode), and re-activated. There's probably a more appropriate function name than "dialog" but that's what I came up with. Handle other ATM hardware (Eagle, etc) besides solos-pci. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@25510 3c298f89-4303-0410-b956-a3cf2f4a3e73
