Subject: [PATCH] ethtool: add register dump support for fjes driver
From: Taku <izumi.taku@...fujitsu.com>
This patch adds the register dump format for FUJITSU Extended
Network device like the following:
# ethtool -d es0
0x0000: OWNER_EPID (Owner EPID) 0x00000001
0x0004: MAX_EP (Maximum EP) 0x00000008
0x0010: DCTL (Device Control) 0x00000000
0x0020: CR (Command request) 0x80000002
0x0024: CS (Command status) 0x80000002
0x0028: SHSTSAL (Share status address Low) 0xE8215304
0x002C: SHSTSAH (Share status address High) 0x00000007
0x0034: REQBL (Request Buffer length) 0x00008028
0x0038: REQBAL (Request Buffer Address Low) 0xEB0A0000
0x003C: REQBAH (Request Buffer Address High) 0x00000007
0x0044: RESPBL (Response Buffer Length) 0x00000018
0x0048: RESPBAL (Response Buffer Address Low) 0xE41E1220
0x004C: RESPBAH (Response Buffer Address High) 0x00000007
0x0080: IS (Interrupt status) 0x00000000
0x0084: IMS (Interrupt mask set) 0x7FE00000
0x0088: IMC (Interrupt mask clear) 0x001F0000
0x008C: IG (Interrupt generator) 0x00010000
0x0090: ICTL (Interrupt control) 0x00000000
