I've run into the same issue and patched net.c a bit to improve the
behavior of the NetConsole use case.  It's a surgical change, though,
not a fundamental change to how the network subsystem works.  Only if
using NetConsole do you get this behavior.  And even if using other
network operations with NetConsole, those other operations mostly
maintain their current behavior.

I'll post the patch at some point in the next month or so when I can
get the time to extract it and test it on modern u-boot.
