[PATCH] S2io: Hardware and miscellaneous fixes
Hi, This patch contains the following hardware related fixes and other miscellaneous bug fixes. 1. Updated the definition of single and double-bit ECC errors 2. Earlier we were allocating Transmit descriptors equal to MAX_SKB_FRAGS. This was causing a boundary condition failure. Need to allocate MAX_SKB_FRAGS+1 descriptors. 3. On some platforms(like PPC), pci_alloc_consistent() can return a zero DMA address. Since the NIC cannot handle zero-addresses, a workaround has been provided. Basically, we don't use such that page. We reallocate. 4. If list_info allocation failed during driver load, check for it during driver exit and return instead of trying to dereference NULL pointer. 5. Increase the debug level of few non-critical debug messages. 6. Reset the card on critical ECC double errors only in case of XframeI since XframeII can recover from such errors. 7. Print copyright message on driver load. 8. Bumped up the driver version no. to 2.0.8.1 Signed-off-by: Ravinandan Arakali <ravinandan.arakali@neterion.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
