The initial patch was meant to allow the user to set any MTU she desires without rebooting the system and changing the kernel bootargs. This however led to problems when the user would manually choose FSL_DPAA_ETH_OPTIMIZE_FOR_IPFWD, because the default MAX_FRAME_SIZE=9600 would remain selected and this wasn't all that obvious.

Until now we considered a buffer recycleable if its size didn't exceed the buffer pool size by more than a certain amount.

fixed-link does not work in 3.8.x, to make XFI work which has no PHY, it's actually not necessary to use fixed-link, otherwise there will be more work and code changes to make fixed-link work in 3.8.x. For now, if driver does not find the phy_node of MAC, just set the mac_dev->phy_dev = NULL and return 0; we can get XFI work and this won't break other ethernet ports.

Tx Confirmation FQs tend, with originating traffic, to generate a high number of portal interrupts. A machine doing only TCP transmits may well end up having more portal interrupts than its Rx peer. By setting the HOLDACTIVE flag on the Tx Confirmation FQs, we significantly reduce the number of portal interrupts in termination tests.

Using 9600 as the default max frame size, if S/G support is available in the DPAA Ethernet driver.

2013-05-24gianfar: Fix tx/rx queue dma_base programming for 36bit modeClaudiu Manoil
For 36 bit mode, TBASEH/RBASEH eTSEC regs need to be programmed with the upper 32-bit part of the DMA base addr of the BD region. This is needed when the BDs are allocated in L2 SRAM above the 4G boundary. For addresses below 4G, which is the default use case, these registers just maintain their default reset value of 0.

2013-05-24gianfar: Add BD rings allocation to L2 SRAMClaudiu Manoil
When this option is enabled the driver will try to allocate the buffer descriptors (BDs) to the L2 SRAM memory, using the powerpc/85xx cache-sram support API for the P1/P2 QorIQ platforms. For this to work, the size and the address of the SRAM region must be provided as kernel boot params. Should the attempt to allocate in L2 SRAM fail, the driver falls back to normal allocation of BDs as before (i.e. to DDR). The gfar_l2sram_en driver module param is provided to allow to disable the allocation to L2 SRAM at driver level (enabled by default). Sysfs stubs allow to enable/diable allocation of BDs to L2 SRAM for individual gianfar devices, as the L2 SRAM is an expensive resource. By default, each device has this feature enabled. This feature also disables the BD L2 stasing feature by default. Stasing however may still be configured per device via sysfs.
