[linuxsh-dev] [PATCH] STNIC changes

[NIIBE Y. <gn...@ch...>]

Hello Kaz, 

I'm using SolutionEngine SH7709A now.  The network driver is sometimes
unstable stalling the communication.  Waiting much time, it works.

Without good reason, I've added curses at stnic_block_output, looking
comment of "oaknet.c".  Then, it works fine.

I don't know if this is good or not.  I don't commit this patch for
myself.  Mitch, could you please add this for the open patches list?
