[ Upstream commit ee4d269eccfea6c17b18281bef482700d898e86f ]
Delay drop data is initiated for PFs that have the capability of rq_delay_drop and are in roce profile.
However, PFs with RAW ethernet profile do not initiate delay drop data on function load, causing kernel panic if delay drop struct members are accessed later on in case a dropless RQ is created.
Thus, stage the delay drop initialization as part of RAW ethernet PF loading process.
