i would send the patch again with this info in the changelog. however, at least on my board, i see no speed difference with this patch. i get about 2.8MiB/s on my bf548-ezkit with and without your change. so, it doesnt break anything that i can see, nor have i been experiencing any problems before, so i dont have a problem with the patch being merged (once a better changelog is added).
I think it's because of we're using Byte Packing enabled and 32-bit reads, but smsc9221 bus is 16-bit wide.
bf548-ezkit config defines CONFIG_SMC911X_16_BIT, but ours - CONFIG_SMC911X_32_BIT.
This is the only difference i've found. -- WBR, Valentin CJSC "NII STT", Russia, Smolensk http://www.niistt.ru
