Section 5.2 says: Inline threshold sizes from 1KB to 256KB can be represented in the Send Size and Receive Size fields. A sender computes the encoded value by dividing the actual value by 1024 and subtracting one from the result. A receiver decodes this value by performing a complementary set of operations. Here, "actual value" means the real size of the buffer. A 1024-octet buffer would result in (1024 / 1024) - 1 = 0. The computation done by the receiver is the inverse: (0 + 1) * 1024 = 1024 I could replace "actual value" by "buffer size, in octets". Would it help if the text also spelled out the inverse computation? -- Chuck Lever -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
