[PATCH] PIO register dump support for 8139 driver

Hi, The following patch adds the pio register dump support for the 8139too.c. The register dump can be now obtained when we are using PIO mode. (eg: ethtool -d eth0 will give the register dump in the PIO mode after this patch is applied.) The patch is against linux-2.6.1-bk4-netdev1. Please do apply. Regards, KK.
