These are all the tg3 changes between 4.19 and 5.0: 750afb08ca71 cross-tree: phase out dma_zalloc_coherent() cddaf02bcb73 tg3: optionally use eth_platform_get_mac_address() to get mac address 3c1bcc8614db net: ethernet: Convert phydev advertize and supported from u32 to link mode 6fe42e228dc2 tg3: extend PTP gettime function to read system clock 310fc0513ea9 tg3: Fix fall-through annotations 22b7d29926b5 net: ethernet: Add helper to determine if pause configuration is supported 70814e819c11 net: ethernet: Add helper for set_pauseparam for Asym Pause af8d9bb2f2f4 net: ethernet: Add helper for MACs which support asym pause 04b7d41d8046 net: ethernet: Fix up drivers masking pause support 58056c1e1b0e net: ethernet: Use phy_set_max_speed() to limit advertised speed Most of the changes are related to PHY settings. I suggest that you check the link settings, including speed, pause, asym pause, etc between the working kernel and the non-working kernel to see if there are differences in the settings.
