You have anything other than N373i ?

Searches are coming up blank. Do you know the manufacturer ? Do you know the speed(s) at which it will run ?

Where did you first hear about it ?

Is NC373i Multifuction NIC from HP? HP only provide a page on how to install driver on driver download page.

The NC373i is the internal nic included within the BL460c (new c-class). It is a Multifunction nic. I did not find any paper where it is written but I did play with this server already and Jumbo frame is supported and fully fonctional :)

This adapter is a newer version that the one in the DL580G4. On the whitepaper:
http://h18004.www1.hp.com/products/quickspecs/12473_div/12473_div.html
You can read:
NOTE: Any NIC, except the NC1020, on the option list can be used for redundancy with the embedded NC371i NIC. When teaming with other NICs or with the embedded NIC, the lack of Jumbo Frames and LSO features on the NC1020 will cause high end NICs to have those features disabled. (e.g. incompatibility issues with the other option NICs for that platform).

To conclude, Any of HP gigabit network adapter (except nc1020) support Jumbo Frame.

I've no idea if it applies to the NIC in question, but a general caveat about using the term "jumbo frames:"

Not all NICs' (or switches') JumboFrame support is created equal. It seems there are some NICs where the definition of JumboFrame is something with an IP MTU less than 9000 bytes. So, when discussing if a NIC/switch supports "Jumbo Frames" it would be good to be explicit about the actual MTU desired and/or supported.

Read this article : http://docs.hp.com/en/783/jumbo_final.pdf#search='jumbo%20frames%20for%20hp%20nic'

The document said all HP Gigabit NIC are support jumbo frame.
