It's actually easier and faster performance-wise to\ninstead get the device from ctx->wg. This semantically makes more sense\ntoo, since ctx->wg->peer_allowedips.seq is compared with\nctx->allowedips_seq, basing them both in ctx. This also acts as a\ndefence in depth provision against freed peers."
