Make `send()` more robust by handling previous ACK #10

Open

davispuh wants to merge 1 commit into drbig:master from davispuh:robust

Syslinux TFTP sometimes sends previous ACK sequence.
This PR allows such behavior making it work :)

Without this PR it would fail like this

ℹ info    [192.168.0.135:49153] New initial packet received
• debug   [192.168.0.135:49153] -> PKT: #<struct TFTP::Packet::RRQ filename="initrd", mode=:octet>
⚠ warning [192.168.0.135:49153:5389 ] Seq mismatch: 53467 != 53466
ℹ info    [192.168.0.135:49153:5389 ] Session ended
