For example, 5.15 doesn't have 7462494408cd: "ethtool: extend ringparam setting/getting API with rx_buf_len" so the mana_ethtool changes requires function parameter modifications to match 5.15. Additional, 5.15 doesn't have 504148fedb85: "net: add skb_[inner_]tcp_all_headers helpers", so previous arithmetic had to be re-implemented. There were a couple of other places where previous functions were maintained rather than bringing in unknown context from the commit. * Most changes were to MANA related source code, so leaning heavily on Microsoft to test there, but it is localized. MANA changes could lead to network instability. * Other changes to scsi and hyperv were small and clean cherry-picks from upstream, so expect little regression risk there. [Other info] * SF#00408239
