1) xnet-DPDK is being used 2) BIG-IP running in an environment where SSSE3 is not available either because CPU is so old that it does not support SSSE3 or SSSE3 has been disabled in VM's config.
Switch to 'sock' driver by adding the following line into /config/tmm_init.tcl, replacing <VENDOR_ID:DEVICE_ID> with the corresponding interfaces' Vendor and Device IDs shown via 'lspci -nn'. For environments in HyperV or Azure, f5f5:f550 should be used for Vendor and Device.
