Unfortunately our e-mails crossed paths... I'll reproduce my comments on v4 here. I'm sure you're going to grow tired of this feedback. I see one thing that I think might be a bug in the third patch, but maybe I'm mistaken, and you can explain why. I tested the code you supplied me last week, and with a bug fix applied I found they worked for: IPA v3.5.1, IPv4 in loopback, checksum enabled and not IPA v4.2, IPv6 using LTE, checksum enabled and not Both of the above tested ICMP, UDP, and TCP. I will retest with version 5 of this series. I did not test with IPA v4.5+, which is unfortunately the main user of this new code. I will try to do so with your updated code, and if all testing passes I'll send a message with "Tested-by" for you to add to your patches. -Alex > Sharath Chandra Vurukala (3): > docs: networking: Add documentation for MAPv5 > net: ethernet: rmnet: Support for ingress MAPv5 checksum offload > net: ethernet: rmnet: Add support for MAPv5 egress packets > > .../device_drivers/cellular/qualcomm/rmnet.rst | 126 +++++++++++++++-- > drivers/net/ethernet/qualcomm/rmnet/rmnet_config.h | 4 +- > .../net/ethernet/qualcomm/rmnet/rmnet_handlers.c | 31 +++-- > drivers/net/ethernet/qualcomm/rmnet/rmnet_map.h | 11 +- > .../net/ethernet/qualcomm/rmnet/rmnet_map_data.c | 151 ++++++++++++++++++++- > drivers/net/ethernet/qualcomm/rmnet/rmnet_vnd.c | 3 +- > include/linux/if_rmnet.h | 27 +++- > include/uapi/linux/if_link.h | 2 + > 8 files changed, 320 insertions(+), 35 deletions(-) >
