I'm thinking we don't need to keep adding two function pointers for each
boolean choice.
I propose adding two operations:
get-flags: return 32-bit (even on 64-bit platforms) flags bitmap
set-flags: set 32-bit flags bitmap
The 32 bits shall be divided as follows:
bits 0-23: ETHTOOL_FLAG_xxx defined in linux/ethtool.h
bits 24-31: driver-specific boolean flags
The driver-specific flags are first enumerated by userland via an
ETHTOOL_GSTRINGS call, using new string set ETH_SS_FLAGS. The first
string returned names the first driver-private flag (bit 24). This also
indicates that driver-private bit 24 is a valid flag for this driver and
network interface.
The overall goal is to replace get-LRO/set-LRO operations with the
setting/clearing of ETH_FLAG_LRO, and as well, provide a more-scalable
ethtool interface.
I'll code this up, along with the associated generic helpers
(net/core/ethtool.c), if there are no objections.
