[lwip-devel] [patch #5822] Handle unused arguments

[Tai-hwa Liang]

Follow-up Comment #8, patch #5822 (project lwip):

Forgot to mention that my patch was tested with all "Inefficient Coding"
warnings turned on in Paradigm Pro, particularly, "Parameter 'ident is never
used" and "'ident declared but never used."

Regarding to unused argument removal, I think that's not that easy without
breaking existing APIs. For example, ip_timer() utilises sys_timeout()
interface, which requires a timeout handler with void argument.
