I suspect what you have is this:
1) MSI K9N v1 - NICs support jumbo frames 2) MSI K9N v3 - NICs do not support jumbo frames
The v3 motherboard has a Realtek RTL8111b nic chip. I found the data sheet (RTL8111B_8168B_Registers_DataSheet_1.0.pdf) and the Jumbo frame support goes to 7552 bytes. Why Suse doesn't support the Jumbo setting is a mystery.
3) Netgear - does not support jumbo frames
Netgear GA311 supports jumbo frames to 7500. http://kb.netgear.com/app/answers/detail/a_id/222 Netgear strongly advises setting jumbo frames on all adapters to the same value.
I can't think of a reason why there would be such a difference between your MSI boards, so I could be way off here.
