bnxt_en: Fix HDS and jumbo thresholds for RX packets
[ Upstream commita056ebcc30
] The recent XDP multi-buffer feature has introduced regressions in the setting of HDS and jumbo thresholds. HDS was accidentally disabled in the nornmal mode without XDP. This patch restores jumbo HDS placement when not in XDP mode. In XDP multi-buffer mode, HDS should be disabled and the jumbo threshold should be set to the usable page size in the first page buffer.
