[ECOS] _control and _start are called several times in the begining

[ECOS] _control and _start are called several times in the begining

[mkhoyila]

Gentlemen

I have an issue (may be it is not an issue) about _control, _send and
_stop functions. As you see from below printout, above functions are
called three times before eCos settles down. Is this normal? Thanks for
your help.

This is indeed normal and has to do with how the network gets 
configured and then reconfigured during initial DHCP negotiations.
