It's correct. The total size of DMA memory is 32KB. Because of that, we cannot use 32KB receive buffer. >From 32KB, we allocate the buffer for transmission and the one for receive. For receive, allocating 16KB + 16byte + (2KB for wrapping) is no problem. -- - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
