- Chelsio Unified Wire Adapters
- Red Hat Enterprise Linux 7.6 or older, which shipped with Chelsio firmware older than version 188.8.131.52
- An IPv6 environment
- Virtualized adapters (VFs)
When using Chelsio Unified Wire Adapters operating in a virutalized mode (VFs are present) on IPv6 networks, programming of the VF MAC address may fail.
Customers with this environment should ensure that they are using firmware version 184.108.40.206 or newer to avoid this IPv6-specific issue. This firmware is newer than that shipped in 7.6, so customers should obtain it from the following links. Future update releases of Red Hat Enterprise Linux 7 will contain newer firmware that delivers this fix.
