net/e1000: fix igc launch time calculation
Improve the launch time calculation logic to handle different scenarios:
- Set launch time to 0 if txtime has expired.
- Set launch time to 0 if txtime exceeds the horizon (beyond the end of
the next Qbv cycle).
- Mark the first flag in the context descriptor when the packet is the
first one scheduled in the next Qbv cycle.
- Create a dummy packet to dirty the current cycle before sending
packets intended for the next Qbv cycle.
Testing was performed on two Intel ADL-S platforms with i226 NICs
connected back-to-back. A DPDK sample application is created to send 10
UDP packets with 20,000 nanosecond intervals and their txtime is set to
the time of the next Qbv cycle. Meanwhile, the tcpdump command below is
used on the link partner to capture the delta of Rx hardware timestamp
of the 10 packets:
tcpdump -ttt -ni enp1s0 --time-stamp-precision=nano -j adapter_unsynced
Without this patch, packets are transmitted immediately as the hardware
interprets their launch time as expired, resulting in 8,384 nanosecond
intervals (wire speed for 1024-byte packets at 1Gbps), as shown in
tcpdump log below:
00:00:00.000000000 IP 192.168.1.100.2 > 224.1.1.1.5: UDP, length 982

00:00:00.000008384 IP 192.168.1.100.2 > 224.1.1.1.5: UDP, length 982
With this patch, packets are properly held until the next Qbv cycle and
transmitted at the intended 20,000 nanosecond intervals, demonstrating
correct launch time behavior, as shown in tcpdump log below:
