It's clear that the vmxnet3 driver (even as of 18.08) supports just a
subset of RSS hash types:
#define VMXNET3_RSS_OFFLOAD_ALL ( \
ETH_RSS_IPV4 | \
ETH_RSS_NONFRAG_IPV4_TCP | \
ETH_RSS_IPV6 | \
ETH_RSS_NONFRAG_IPV6_TCP)
Are there plans to add support for other hash types (like
ETH_RSS_NONFRAG_IPV4_UDP), or is this an architectural limitation of
vmxnet3?
The documentation could be more explicit about these limitations:
36.2. Features and Limitations of VMXNET3 PMD
In release 1.6.0, the VMXNET3 PMD provides the basic functionality of
packet reception and transmission. There are several options
available for filtering packets at VMXNET3 device level including:
1. *MAC Address based filtering*:
* Unicast, Broadcast, All Multicast modes - SUPPORTED BY DEFAULT
* Multicast with Multicast Filter table - NOT SUPPORTED
* Promiscuous mode - SUPPORTED
* *RSS based load balancing between queues - SUPPORTED*
Thanks,
