Bug ID 1564
Summary Broadcom doesn't receive network packets via RX Interrupt (in= finite lock rte_epoll_wait)
Product DPDK
Version 24.07
Hardware x86
OS Linux
Status UNCONFIRMED
Severity critical
Priority Normal
Component ethdev

Target Milestone --- 

The rte_epoll_wait function is nev=
er 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:=20
htt=
ps://docs.broadcom.com/docs/NXE_Linux_niccli_231.0.162.1

Command:=20
./niccli -i 1 install -online

dcom.com/us/en/storage-and-ethernet-connectivity/ethernet-nic-controllers/b=
cm957xxx/adapters/software-installation/updating-the-firmware/updating-the-=
firmware-online.html

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):
https://pastebin.com/VH6PLiTU

5. Run the binary generated by the previous compilation

You will see the error, if you remove rte epoll_wait the ping works normall=
y,
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.=20

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