From d0a42d6fc8eaf1b64f62b0bbc3b829b756eacf57 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Sun, 15 May 2016 03:04:46 -0400 Subject: [PATCH] bnxt_en: Reduce maximum ring pages if page size is 64K. The chip supports 4K/8K/64K page sizes for the rings and we try to match it to the CPU PAGE_SIZE. The current page size limits for the rings are based on 4K/8K page size. If the page size is 64K, these limits are too large. Reduce them appropriately. Signed-off-by: Michael Chan Signed-off-by: David S.
