Even if the MAC supports multiple PHY interfaces, you should activate the EEE mode only when the MAC is operating with GMII, MII, or RGMII interface." Applying this restriction solves a stability issue observed on Amlogic gxl platforms operating with RMII interface and the internal PHY.

We do not update the hardware as long as we receive skb:s with the same value in gso_size. During a network device down/up cycle (mapped to stmmac_release() and stmmac_open() callbacks) we issue a reset to the hardware and it forgets the setting for mss. However we did not zero out our mss variable so the next transmission of a gso packet happens with an undefined hardware setting. This triggers a hang in the TSO engine and eventuelly the netdev watchdog will bark.

These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

However, priv->tx_path_in_lpi_mode is assigned using the return value from host_irq_status(). So for dwmac4, priv->tx_path_in_lpi_mode was always false, so stmmac_tx_clean() would always try to put us in eee mode, and stmmac_xmit() would never take us out of eee mode. To fix this, make host_irq_status() read and return the LPI irq status also for dwmac4. This also increments the existing LPI counters, so that ethtool --statistics shows LPI transitions also for dwmac4. For dwmac1000, irqs are enabled/disabled using the register named "Interrupt Mask Register", and thus setting a bit disables that specific irq. For dwmac4 the matching register is named "MAC_Interrupt_Enable", and thus setting a bit enables that specific irq. Looking at dwmac1000_core.c, the irqs that are always enabled are: LPI and PMT. Looking at dwmac4_core.c, the irqs that are always enabled are: PMT. To be able to read the LPI irq status, we need to enable the LPI irq also for dwmac4.
