Broadcom doesn't receive network packets via RX Interrupt (infinite lock rte_epoll_wait)

Bug ID: 1564
Summary: Broadcom doesn't receive network packets via RX
Interrupt (infinite lock rte_epoll_wait)
Product: DPDK
Version: 24.07
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: critical
Priority: Normal
Component: ethdev
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---

The rte_epoll_wait function is never returning, I believe that the interrupts are not being properly configured for the bnxt_en driver after upgrade.

Bug NIC: Broadcom NetXtreme-E BCM57508

It is important to note that the same code works on Mellanox NIC, more precisely Mellanox ConnectX-5 Ex MT28800

Steps to reproduce:
1. Update the NIC firmware using niccli utility
Download:
https://docs.broadcom.com/docs/NXE_Linux_niccli_231.0.162.1

Command:
./niccli -i 1 install -online

2. Change IP 67.159.40.18/24 to your network IP

3. Change IP 67.159.40.17 to your default gateway

4. Compile the code below

The final C++ code (cpp):

5. Run the binary generated by the previous compilation

You will see the error, if you remove rte epoll_wait the ping works normally, but if you use rte_epoll_wait it will never return

If necessary, I can provide access to my dedicated server that uses this specific Broadcom NIC.

I can also provide access to the VNC console to access the server even after starting the application.
