Subject: Re: UDP Checksum offload with X550-T2

I found examples that showed the last two lines from my prior email in
reversed order (that is, set ip_hdr->hdr_checksum = 0 before calling
rte_ipv4_phdr_cksum()). I switched those lines and it sometimes works
now, but eventually fails again (after several hundred thousand
packets) whereas the tx_burst() was reliable before I tried to use
offload. Is there still something else wrong here?
