[LU-15851] Adjust niov checks for large MD

• Status: Resolved
• Project: Lustre
• Affects Version/s: Lustre 2.15.0
• Fix Version/s: Lustre 2.16.0
• Type: Bug
• Priority: Minor
• Reporter: Chris Horn
• Assignee: Chris Horn
• Resolution: Fixed
• Severity: 3

Description

An LNet user can allocate a large contiguous MD. That MD can have >
LNET_MAX_IOV pages which causes some LNDs to assert on either niov
argument passed to lnd_recv() or the value stored in
lnet_msg::msg_niov. This is true even in cases where the actual
transfer size is <= LNET_MTU and will not exceed limits in the LNDs.
