[dpdk-dev] [PATCH] app/test: fix crash of lpm test

[Olivier Matz]

The test recently added accesses to lpm->tbl8[ip >> 8] with is much
larger than the size of the table, causing a crash of the test
application.

Fix this typo by replacing tbl8 by tbl24.

Fixes: 231fa88ed522 ("app/test: verify LPM tbl8 recycle")

Hi Wei,

I don't know lpm very well and I did not spend much time to understand
the test case. I guess that's the proper fix, but please check carefully
that I'm not doing something wrong :)

Thanks,
Olivier
