+Subject: [PATCH] RDMA/erdma: Update default EQ depth to 4096 and max_send_wr
+ to 8192
+References: bsc#1012628
+Patch-mainline: 6.2.12
+Git-commit: 6256aa9ae955d10ec73a434533ca62034eff1b76
+
+[ Upstream commit 6256aa9ae955d10ec73a434533ca62034eff1b76 ]
+
+Max EQ depth of hardware is 32K, the current default EQ depth is too small
+for some applications, so change the default depth to 4096.
+Max send WRs the hardware can support is 8K, but the driver limits the
+value to 4K. Remove this limitation.
+
+Fixes: be3cff0f242d ("RDMA/erdma: Add the hardware related definitions")
+Fixes: db23ae64caac ("RDMA/erdma: Add verbs header file")
