Function 52, subfunction 2 - set network driver configuration.
Parameters:
- eax = 52 - function number
- ebx = 2 - subfunction number
- ecx = configuration dword; if low 7 bits derivate the number 3,
function [re-]initializes Ethernet-card, otherwise
Ethernet turns off
Returned value:
- if Ethernet-interface is not requested, function returns eax=2,
but this can be changed in future kernel versions
- if Ethernet-interface is requested, eax=0 means error
(absence of Ethernet-card), and nonzero value - success
Remarks:
- Configuration dword can be read by subfunction 0.
- The kernel does not use this variable. The value of this
variable, subfunction 0 and part of subfunction 2, which set it,
is represented doubtful.
