1. A network adapter, comprising:
a port, to send packets to a network in accordance with a Remote Direct Memory Access over Converged Ethernet (RoCE) protocol; and
one or more circuits, to:
decide whether a packet is permitted to undergo Adaptive Routing (AR) in being routed through the network;
mark the packet with an indication of whether the packet is permitted to undergo AR, including, in response to the packet meeting a defined condition, marking the packet as ineligible to undergo AR regardless of whether the packet is eligible or not; and
send the marked packet to the network via the port.
