It's hard to tell what you're doing, but I'd suggest downloading the datasheet and looking at the bits in the register you just referred to.
The easiest way to get the data sheet is to google for "i350 data sheet" and select the version on the intel web site. You may want to download the specification update as well. A quick check of 0x3400 0000 looks to show a problem in queue 1, a malicious driver behavior from a VLAN Insertion error. Sounds like you're doing something odd. 0x7400 0000 is the same error on a different queue.

I've passed intel igb vf to my VM through sr-iov but "igb 0000:82:00.1 enp130s0f1: malformed Tx packet detected and dropped, LVMMC:0x34000000" pops up every 2 seconds on dmesg. I am using intel i350-T4 nic for sr-iov I was searching on the internet what is "LVMMC" and what "0x34000000" means but only thing I could find was the link above. Sometimes "LVMMC:0x74000000" errors pops up too. What triggers LVMMC? I've turned off vf spoofcheck through ip utility in linux but seems like it doesn't work. (Still kernel warns me that VM tried to change MAC address which was set administratively, and reload the vf driver) Thank you in advance.
