The script does spotlight Checksum Errors on the Intel ethernet ports -
should I be concerned with those errors?
#sysctl dev.ix. | grep checksum
dev.ix.3.mac_stats.checksum_errs: 26
dev.ix.2.mac_stats.checksum_errs: 20844466
dev.ix.1.mac_stats.checksum_errs: 16621802
dev.ix.0.mac_stats.checksum_errs: 8562140
netstat -i" doesn't show any errors.
I am reading up on tuning for a router here:

and here:

Adding in " -tso4 -tso6 -lro" flags as well as adjusting the
kern.random.harvest.mask - I keep hoping one of them will help with the
+Checksum Errors, but I guess if the packets are bad getting to the box,
then the errors are what they are: errors.
