ethernet: T3048: drop static smp-affinity for dynamic performance tuning
After migrating the ethernet interfaces from the good old Perl days the smp-affinity node yet has no effect anymore as the code is still missing (my bad, sorry). Drop the smp-affinity node and rather use tuned instead with the network-throughput or network-latency profile. - network-throughput: Profile for throughput network tuning. It is based on the throughput-performance profile. It additionaly increases kernel network buffers. - network-latency: Profile for low latency network tuning. It is based on the latency-performance profile. It additionaly disables transparent hugepages, NUMA balancing and tunes several other network related sysctl parameters. I'd set network-throughput as the default on a new set system option performance <throughput | latency> CLI node which is present in the default configuration. https://access.redhat.com/sites/default/files/attachments/201501-perf-brief-low-latency-tuning-rhel7-v2.1.pdf
