SOLUTION:---------struct igbvf_buffer {dma_addr_t dma;struct sk_buff *skb;`enter code here`union {/* Tx */struct {unsigned long time_stamp;u16 length;u16 next_to_watch;u16 mapped_as_page;};/* Rx */struct {struct page *page; <--------------- No 1u64 page_dma;unsigned int page_offset;};};struct page *page; <------------ No 2};Hmm conflict of a member with a transparent union.Maybe older gccs didn‘t catch that. But it looks very brokenComment second pointer.
