From 3ddeac6705aba31b7528c7d7a528eabb74475622 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 18 Oct 2018 11:34:55 -0700 Subject: tools: bpftool: use 4 context mode for the NFP disasm The nfp driver is currently always JITing the BPF for 4 context/thread mode of the NFP flow processors. Tell this to the disassembler, otherwise some registers may be incorrectly decoded.
