-Subject: [PATCH] GRETH: added greth_compat_mode module parameter
-
-The greth_compat_mode option can be used to set a GRETH GBit capable MAC
-in operate as if the GRETH 10/100 device was found. The GRETH GBit supports
-TCP/UDP checksum offloading, unaligned frame buffers, scatter gather etc.
-Enabling this mode allows the developer to test the GRETH 10/100 device
-without all features mentioned above on a GBit MAC capable of the above.

-Subject: [PATCH] GRETH: resolve SMP issues and other problems
-
-Fixes the following:
-1. POLL should not enable IRQ when work is not completed
-2. No locking between TX descriptor cleaning and XMIT descriptor handling
-3. No locking between RX POLL and XMIT modifying control register
-4. Since TX cleaning (called from POLL) is running in parallel with XMIT
-   unnecessary locking is needed.
-5. IRQ handler looks at RX frame status solely, this is wrong when IRQ is
-   temporarily disabled (in POLL), and when IRQ is shared.
-6. IRQ handler clears IRQ status, which is unnecessary
-7. TX queue was stopped in preventing cause when not MAX_SKB_FRAGS+1 descriptors
-   were available after a SKB been scheduled by XMIT. Instead the TX queue is
-   stopped first when not enough descriptors are available upon entering XMIT.
-
-It was hard to split up this patch in smaller pieces since all are tied
-together somehow.
-
-Note the RX flag used in the interrupt handler does not signal that interrtupt
-was asserted, but that a frame was received. Same goes for TX. Also, IRQ is not
-asserted when the RX flag is set before enabling IRQ enable until a new frame is
-received. So extra care must be taken to avoid enabling IRQ and all descriptors
-are already used, hence dead lock will upon us. See new POLL implementation that
-enableds IRQ then look at the RX flag to determine if one or more IRQs may have
-been missed. TX/RX flags are cleared before handling previously enabled
-descriptors, this ensures that the RX/TX flags are valid when determining if IRQ
-should be turned on again.
-
-By moving TX cleaning from POLL to XMIT in the standard case, removes some
-locking trouble. Enabling TX cleaning from poll only when not enough TX
-descriptors are available is safe because the TX queue is at the same time
-stopped, thus XMIT will not be called. The TX queue is woken up again when
-enough descriptrs are available.
-
-TX Frames are always enabled with IRQ, however the TX IRQ Enable flag will not
-be enabled until XMIT must wait for free descriptors.
-
-Locking RX and XMIT parts of the driver from each other is needed because the
-RX/TX enable bits share the same register.

-[PATCH] sparc32: Add -Av8 to assembler command line.
-
-Newer version of binutils are more strict about specifying the
-correct options to enable certain classes of instructions.
-
-The sparc32 build is done for v7 in order to support sun4c systems
-which lack hardware integer multiply and divide instructions.
-
-So we have to pass -Av8 when building the assembler routines that
-use these instructions and get patched into the kernel when we find
-out that we have a v8 capable cpu.
