Make the code flow a little better for 80 columns.
Use a consistent style for the RX and TX rings allocation. Use BIT macro. Use a temporary unsigned int entries for (1<<size). Remove the OOM messages as they duplicate the generic OOM and dump_stack() provided by the memory subsystem. Reflow allocs to 80 columns.
Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Don Fry <pcnet32@frontier.com> --- V2: Use pcnet32 as patch prefix, amd is too generic
Still depends on patch 1/22: pci-dma-compat: Add pci_zalloc_consistent helper
