[dpdk-dev] [PATCH] config: disable CONFIG_RTE_SCHED_VECTOR for arm

[Jerin Jacob]

Commit 42ec27a0178a causes compiling error on arm, as RTE_SCHED_VECTOR
does support only SSE intrinsic, so disable it till we have neon support.

Fixes: 42ec27a0178a ("sched: enable SSE optimizations in config")

You would not need to update 4 files if the 3 last ones were including the
first one.
I think having an arm config base would also make clearer the differences
between the arm platforms.

armv7 and armv8 config parameters are quite different.I think we
can converge all the common configs of defconfig_arm64-*

Yes, For armv8, I can update arm64-armv8a-linuxapp-gcc as a base config
and only absolute delta changes can be added to thunderx/xgene1 config.

I will send out the next revision with arm64-armv8a-linuxapp-gcc as
a base config.

Thanks
Jerin
