Why don't you use fixed size members?
And we can eliminate 8bit hole.

struct x25_dte_facilities {
     u32             calling_len
     u32             called_len;
     u8              calling_ae[20];
     u8              called_ae[20];
     u8              min_throughput;
     u8              expedited;
     u16             delay_cumul;
     u16             delay_target;
     u16             delay_max;
};
