Subject[PATCH] igc: remove unused igc_priv_flags_strings array
Date
clang points out that the igc_priv_flags_strings[] array is never
referenced, aside from being used for calculating its length:

drivers/net/ethernet/intel/igc/igc_ethtool.c:9:19: error: variable 'igc_priv_flags_strings' is not needed and will not
be emitted [-Werror,-Wunneeded-internal-declaration]
static const char igc_priv_flags_strings[][ETH_GSTRING_LEN] = {

A similar array is present in several other intel ethernet drivers,
but all the others use it in their .get_strings() callback, which
igc does not implement (yet).

Probably it should be implemented, but as I have no way of testing
it, this does the simpler alternative of removing the array to
get rid of the warning.

Fixes: 8c5ad0dae93c ("igc: Add ethtool support")
