GMAC devices newer than databook 3.40 has an embedded timer that can be used for mitigating the number of interrupts. So this patch adds this optimizations. At any rate, the Rx watchdog can be disable (on bugged HW) by passing from the platform the riwt_off field. In this implementation the rx timer stored in the Reg9 is fixed to the max value. This will be tuned by using ethtool. V2: added a platform parameter to force to disable the rx-watchdog for example on new core where it is bugged. V3: do not disable NAPI when Rx watchdog is used. V4: a new extra statistic field has been added to show the early receive status in the interrupt handler. This patch also adds an extra check to avoid to call napi_schedule when the DMA_INTR_ENA_RIE bit is disabled in the Interrupt Mask register.

This patch adds a new schema used for mitigating the number of transmit interrupts. It is based on a SW timer and a threshold value. The timer is used to periodically call the stmmac_tx_clean function; the threshold is used for setting the IC (Interrupt on Completion bit). The ISR will then invoke the poll method. Also the patch improves some ethtool stat fields. V2: review the logic to manage the IC bit in the TDESC that was bugged because it didn't take care about the fragments. Also fix the tx_count_frames that has not to be limited to TX DMA ring. Thanks to Ben Hutchings. V3: removed the spin_lock irqsave/restore as D. Miller suggested.

This patch is to extend the number of MAC address registers for 16 to 32. In fact, other new 16 registers are available in new chips and this can help on perfect filter mode for unicast. This patch also fixes the perfect filtering mode by setting the bit 31 in the MAC address registers. v2: fixed Coding Style.

This patch adds the PCI support (as EXPERIMENTAL) this has been also tested on XLINX XC2V3000 FF1152AMT0221 D1215994A VIRTEX FPGA board. To support the PCI bus the main part has been reworked and both the platform and the PCI specific parts have been moved into different files.

This avoids unnecessary casting and adds the ioaddr in the private structure. This patch also removes many warning when compile the driver. Signed-off-by: NGiuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand. Compile tested x86 allmodconfig only. Signed-off-by: NJoe Perches <joe@perches.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch moves the dma related functions (interrupt, start, stop etc.) out from the main driver code. This will help to support new DMA engines. Signed-off-by: NGiuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
