    iwlwifi: mvm: Enable Rx Checksum hw · 93190fb0
    Avri Altman authored
    TCP software implementation on the host requires extensive computing
    power.  Offloading even some of the TCP/IP stack to the NIC might save
    a significant overhead. In order to enable this feature on our hw,
    we need to configure it first. Once done, we mark this capability,
    to be advertised later to the OS via ieee80211_register_hw.
    The driver Rx indications for TCP Checksum is integrated within the
    standard Rx status. The driver responds to those indications as follows:
    If the frame was tested by hw and checksum ok report CHECKSUM_UNNECESSARY.
    Otherwise, report CHECKSUM_NONE.
