PSOD in vmk_PktFrameLenSet

[kamalpr]

Hello,

I got a PSOD when i called vmware's api function vmk_PktFrameLenSet()  inside my nic driver. The arguments to the function were:-

vmk_PktFrameLenSet(0x45ba60dfa3c0, 68)

The first parameter is not NULL and valid, and the length is also valid. The same function was called several times with the same argument when receiving packets in an isr. so, it is not a functional problem or a problem  of passing bad arguments according to me.

The relevant stack trace for vmware is given below.. Can someone tell me if it is a problem from vmware's side:-
