The application then updates the mbuf ol_flags and sets the PKT_TX_UDP_SEG flag. Then based on the tso_segs and tso_mss fields in the mbuf the PMD can indicate the UDP GSO transmit request to the hardware. This feature is supported on Thor2 and will be enabled when the firmware sets the UDP GSO support via the HWRM_FUNC_QCAPS.
