MSA 2040 IP jumbo packet size with VMware ESXi 6.5 hosts

Hello,

I have three ESXi 6.5 hosts connected through Cisco switches to a MSA 2040 using iSCSI.  Jumbo frames have been enabled in each device.  

MSA 2040 - Jumbo Frames enabled

Cisco  - jumbomtu 9000

ESXi - vmk's nic settings MTU 8900 (per https://www.stephenwagner.com/2016/11/05/hpe-msa-2040-jumbo-frames-and-mtu-configuration/)

When I perform a tcpdump-uw on the ESXi host the largest packet size I see is 4144. I would think I would see something in the 8000 range.   A vmkping -d -s 8872 command works successfully.  

Is 4144 the max tcp packet size I should expect?

Thank you,

Altoon
