Subject: [PATCH v2 0/3] e1000e,igb,ixgbe: add registers etc. printout code
 just before resetting adapters

Hi Jeff,

This patchset is the update version of "register etc. printout code" patch. (sorry
for late reply)
The old one is http://marc.info/?l=linux-netdev&m=126286127208276&w=2

v1 -> v2:
 - replaced hexdump() with print_hex_dump()
 - changed the register printout inplementation (for-switch-case -> data-driven-table)

However the default value of "dump_flag" is not changed (still 1).
The reason I didn't change is
 - I think HW index (TDH,TDT..) and SW index (NTC,NTU) are at least necessary
 - the amount of default output is not so large (see bellow)
 - the adapter resetting problem doesn't happen frequently


The default output sample (NOT the actual hangup case) is as follows:
