Thanks for all the feedback on the patch. Refactoring the ibmvnic reset 
functions is something we plan to evaluate, as this would potentially 
simplify the reset code. In the mean time, the proposed patch is simple, 
and has been validated in our test environment to solve an issue 
resulting in vnic interfaces getting stuck in an offline state following 
a vnic timeout reset. Given that, I suggest we merge this patch while we 
look at further optimizations in future. I will submit a V3 patch
