Link™ Capture Software 12.2.4 for Linux
2020-05-28 14:26

This is a maintenance release 12.2.4 of the Napatech Link Capture 12.2 software, resolving an internal RAB-timeout message and adding support for a 100G BiDi "Rx-only" module.

The Napatech Link™ Capture 12.2 software release series, introduces powerful features for test & measurement applications. Nanosecond hardware transmit and receive timestamping enables precision network roundtrip delay and jitter measurements. The solution also includes advanced features for error and network jitter simulation. All of this is supported for 10G, 25G, 40G and 100G network speeds. The release also includes support for Cisco FabricPath encapsulation and bug-fix’es. Please refer to the documentation and release notes for details on the new features, bugfix’es and which SmartNIC products the new features apply to.

Feature summary:
   - Tx time stamp inject at offset relative to L3/L4 headers
   - L2 and L3/L4 (IP/TCP/UDP) Tx Checksums Generation
   - L2 and L3/L4 (IP/TCP/UDP) Rx Checksums Verification
   - Cisco FabricPath encapsulation

Package version: 12.2.4
Driver version:     3.20.4
FPGA versions:     28-xx
