However, build_skb() can fail under memory pressure.\nThis results in a kernel panic because the skb to reserve is NULL.\n\nAdd a check in case build_skb() failed to allocate and return NULL.\n\nThe NULL return is handled correctly in callers to qede_build_skb()."

Sin embargo, build_skb() puede fallar bajo presi\u00f3n de memoria. Esto da como resultado un p\u00e1nico del kernel porque el skb a reservar es NULL. Agregue una verificaci\u00f3n en caso de que build_skb() no pueda asignar y devuelva NULL. El retorno NULL se maneja correctamente en los llamadores a qede_build_skb()."
