Subject: pipeline: fix instruction label check
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=55095ccb7fdda113186e3191760a5cf0b0e8d28d

pipeline: fix instruction label check

The instruction_data array was incorrectly indexed, which resulted in
the array index getting out of bounds and sometimes segfault.

Fixes: a1711f (“pipeline: add SWX Rx and extract instructions“)
