Hello:

This patch was applied to netdev/net.git (main)
by Jakub Kicinski [off-list ref]:

The original code used DMA_ATTR_FORCE_CONTIGUOUS, which could exhaust
the CMA pool when a large number of VFs were requested.

Fix this by switching to the DMA streaming API. This is equivalent on
Octeon platforms, which provide full I/O coherency via the SMMU.
