[Ns-developers] [ns 2.33] return value of WirelessPhyExt::discard()

[antoine.trux@nokia.com]

Hi,

Function WirelessPhyExt::discard() returns a value of type `int'.
However:

1) The semantics of the value returned by WirelessPhyExt::discard() is
nowhere documented.

2) The value returned by WirelessPhyExt::discard() is always equal to 0.

3) The value returned by WirelessPhyExt::discard() is never used (it is
sometimes assigned to a variable, but in those cases the variable is
never used).

Therefore, I would suggest to simplify the code by having
WirelessPhyExt::discard() return `void'.
